IPC: H04B3/04
Filed: 1992-12-04
Abstract: For avoiding error propagation as a result of decision feedback equalization, the data to be transmitted are coded with a coder 2 which has a transfer function substantially inverse to the transfer function of the channel 4. Consequently, instantaneous decisions about the received symbol may be made at the receiver 6 without intersymbol interference causing a disturbance. 
     If the channel transfer function differs from the transfer function of the precoder 2, intersymbol interference will again occur, so that the symbol error rate will increase. 
     In order to restrict this increase of the symbol error rate as much as possible, the receiver comprises a cascaded circuit of an adaptive filter 18 which has an inverse transfer function to that of the channel and a decoder 21 which has a inverse transfer function to that of the precoder 2.

Abstract: A method and apparatus for controlling the execution of image processing operations carried out on an array of image signals, the specific operations having been identified by a plurality of predefined windows. The windows are divided into a plurality of non-overlapping tiles, the boundaries of which correspond to transitions from one window region to another. Each tile therefore defines an exclusive region within the array of image signals, and the image processing operations to be applied to the signals within the boundaries of that region. Tile data is stored in one of two memory banks (A,B), thereby enabling bank switching and reprogramming of the device in real-time to permit management of complex window shapes. The apparatus is designed to efficiently manage the identification of tile regions while minimizing the required decoding hardware. The apparatus also provides flexibility of programming resulting in greater efficiency of memory usage.

Abstract: A static RAM cell having first and second differentially connected lines reads binary information stored in the cell by providing a current through the cell and the first line to read a binary "1" or through the cell and the second line to read a binary "0". First and second transistors in a pre-amplifier respectively connected in the first and second lines provide outputs respectively representing a binary "1" and a binary "0". The first and second transistors pass control currents respectively through third and fourth transistors to produce bias currents in one of the first and second transistors when reading currents are not passing through that transistor and the cell. The control of the third and fourth transistors increases the frequency at which information is read from the cell and is amplified. In this improvement, the bias current in the line providing an output at each instant is reduced by respectively providing a negative feedback from the outputs (e.g. the drains) of the first and second transistors to control the inputs (e.g. the gates) of the third and fourth transistors. This reduces power losses while increasing the frequency at which binary information is read from the cell. The frequency may be further increased by including an impedance in the control circuitry to the third and fourth transistors to delay the response of the third and fourth transistors. Pairs of pre-amplifiers for different bit and word lines may be connected in parallel to provide further increases in the frequency response and further power losses.

Abstract: The present invention includes a system and method for minimizing interference between two radio stations, e.g., a mobile radio telephone and a fixed base station, at the initiation of a radio communication. A mobile station initiates a random access at the lowest power level and increases the transmission power level until the base station detects the access signal. Once detected, the power level of the message is maintained at the detected level so that the signal interference is avoided. The present invention also provides a mechanism for synchronizing random access communications between mobile stations and the base station despite variation in distances between the mobile and base stations.

Abstract: In a modulation system, a demodulator demodulates an intermediate frequency modulated signal and outputs an analog-baseband signal, and an analog-digital converter analog-digital converts this baseband signal. The adaptive matched filter inputs the output of the analog-digital converter and makes symmetrical the impulse response of the propagation path. The decision feedback equalizer inputs the output of the adaptive matched filter and eliminates the intersymbol interference. A reset circuit judges the fading type using tap coefficients within the decision feedback equalizer, and stops the operation of the adaptive matched filter in cases of minimum phase shift type fading. The adaptive matched filter is constructed so as to operate in an intermediate frequency band as well as in a baseband.

Abstract: The invention is comprised of a method which allows the user to convert several data layers from one GIS into another. The user creates a template map of the area of interest. The template is an "all points" map which, when graphed, would appear as a black polygon identical in shape to the area of interest. Using the first GIS, the template is converted to a file in bit-mapped format. All zero bits in this file are identified and their position in the file noted. This information is referred to as the transform function. For each data layer to be converted, the first GIS is used to display a map of the proper extent. This display is converted to a file in bit-mapped format and the transform function used to delete non-data bits which correspond to the zero bits identified in the template file. The resulting, modified, bit-map is imported into the second GIS.
