Due to the explosive demands for high speed wireless services, such as wireless Internet, email and cellular video conferencing, digital wireless communications has become one of the most exciting research topics in electrical and electronic engineering field. The never-ending demand for such personal and multimedia services, however, demands technologies operating at higher data rates and broader bandwidths. In addition, the complexity of wireless communication and signal processing systems has grown considerably during the past decade. Therefore, powerful computer­aided techniques are required for the process of modeling, designing, analyzing and evaluating the performance of digital wireless communication systems. In this paper we discuss the basic propagation mechanisms affecting the performance of wireless communication systems, and present a simple, powerful and efficient way to simulate digital wireless communication systems using Matlab. The simulated results are compared with the theoretical analysis to validate the simulator. The simulator is useful in evaluating the performance of wireless multimedia services and the associated signal processing structures and algorithms for current and next generation wireless mobile communication systems.

Millimeter-wave path loss between two cars was measured to obtain the general applicable distance for inter-vehicle communication systems in real environments. An abrupt and substantial increase in path loss due to interruption, curves, and different-lane traveling has been a major concern in inter-vehicle communications. The path loss measurements were carried out using 60-GHz CW radiowaves and standard horn antennas on metropolitan highways and regular roads. Because the propagation loss is traffic-dependent, the highways were classified into uncrowded and crowded highways, and the regular roads were classified into uncrowded and crowded roads. The path loss for the highways exhibited 2nd-power-law attenuation and that for the regular roads exhibited 1st-power-law attenuation with an increase in inter-vehicle distance. Additional losses of 15 dB for the highways and 5 dB for the regular roads were observed when the inter-vehicle distance was more than approximately 30 m. Thus, we were able to demonstrate millimeter-wave inter-vehicle communications at an inter-vehicle distance of more than 100 m.

Error correction codes are widely used in digital communications to improve the Quality of Service. The Quality of Service is typically expressed in terms of maximum acceptable frame error rate and bit error rate. The key implementation issues for most powerful error correction codes are the complexity and overall encoding/decoding latency. In this paper, short-frame turbo product codes for real-time wireless multimedia communications are proposed. Performance of the proposed turbo codes is studied through simulations on an additive white Gaussian noise (AWGN) channel. The obtained results indicate that the performance of these codes is quite exceptional given their decoding complexity.

The paper describes an attempt to create an efficient dedicated MP3-decoder, according to the MPEG-1 Layer III standard. A new method of Inverse Modified Discrete Cosine Transform by optimization on the Discrete Cosine Transform (DCT) matrix is proposed and an assembler program for Digital Signal Processor is developed. In addition, a program to calculate DCT using Lee's algorithm for any matrix of the size 2M is created. The experimental results have proven that the decoder is able to stream and decode MP3 in real time.

The optical transfer function (OTF), as an objective measure of the quality of optical and electro-optical systems, is closely related to the point spread function (PSF) and other derived characteristics, such as the modulation transfer function (MTF) and the phase transfer function (PTF). The paper focused to the use a generalized OTF, which is primarily dedicated to the description of linear space invariant systems (LSI), for the purpose of sampled structures of image sensors (e.g. CCD, CMOS, CID), and to implement the derived results while utilizing the graphical user's interface (GUI) in Matlab. The model used considers the effects of the detector photo sensitive area, sampling process, as well as other CCD specific parameters, such as the charge transfer efficiency (CTE) or diffusion in order to derive the overall MTF shape. The paper also includes an experimental measurement in the real system and a comparison with the results of modeling.

In image processing and transmission, interpolation and extrapolation are of great importance whenever missing pixels have to be filled in, and many methods have been proposed to solve this problem. In this paper we present a method for extrapolating the missing data with an existing set of basis functions of a selected orthogonal transform. The best extrapolation is found according to linear approximation theory as a weighted sum of basis functions, where coefficients of the sum are solutions of the derived matrix equation.

In this paper some Human Visual System (HVS) models used in digital image watermarking are presented. Four different HVS models, which exploit various properties of human eye, are described. Two of them operate in transform domain of Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). HVS model in DCT domain consists of Just Noticeable Difference thresholds for corresponding DCT basis functions corrected by luminance sensitivity and self- or neighborhood contrast masking. HVS model in DWT domain is based on different HVS sensitivity in various DWT subbands. The third presented HVS model is composed of contrast thresholds as a function of spatial frequency and eye's eccentricity. We present also a way of combining these three basic models to get better tradeoff between conflicting requirements of digital watermarks. The fourth HVS model is based on noise visibility in an image and is described by so called Noise Visibility Function (NVF). The possible ways of exploiting of the described HVS models in digital image watermarking are also briefly discussed.

The paper deals with an algorithm of texturing of the surface of 3D human head model. The proposed algorithm generates a texture consequently of several camera frames of the input video sequence. The texture values from the camera frames are mapped on the surface of the 3D human head model using perspective projection, scan line and 3D motion estimation. To decrease the number of camera frames a filling of empty places by a simple interpolation method has been done in the texture plane.

Two models for objective assessment of compressed video quality and results from subjective and objective tests of several low bit-rate video coders are introduced in this paper. First model is based on mathematical measures that describe perception of video distortion by human eye. Second model for quality evaluation is based on human visual system (HVS) characteristics. Obtained quality values from both models have been compared with subjective results. Both models are computationally efficient and produce results that are correlated with subjective results.

An SN (sinusoids plus noise) model is a spectral model, in which the periodic components of the sound are represented by sinusoids with time-varying frequencies, amplitudes and phases. The remaining non-periodic components are represented by a filtered noise. The sinusoidal model utilizes physical properties of musical instruments and the noise model utilizes the human inability to perceive the exact spectral shape or the phase of stochastic signals. SN modeling can be applied in a compression, transformation, separation of sounds, etc. The designed system is based on methods used in the SN modeling. We have proposed a model that achieves good results in audio perception. Although many systems do not save phases of the sinusoids, they are important for better modelling of transients, for the computation of residual and last but not least for stereo signals, too. One of the fundamental properties of the proposed system is the ability of the signal reconstruction not only from the amplitude but from the phase point of view, as well.

This paper presents a new motion estimation algorithm to improve the performance of the existing searching algorithms at a relative low computational cost. We try to amend the incorrect and/or inaccurate estimate of motion with higher precision by using adaptive weighted median filtering and its modifications. The median filter is well-known. A more general filter, called the Adaptively Weighted Median Filter (AWM), of which the median filter is a special case, is described. The submitted modifications conditionally use the AWM and full search algorithm (FSA). Simulation results show that the proposed technique can efficiently improve the motion estimation performance.
