Abstract: A carrier frequency offset detecting apparatus of a digital receiver and a carrier frequency offset detecting method thereof. The carrier frequency offset detecting apparatus includes correlators to calculate individual correlation values by employing pseudo-noise sequences; at least one conjugate signal generation unit to generate a conjugate complex number for each of the correlation values; at least one multiplier to multiply the individual conjugate complex numbers with the individual correlation values of the neighbored correlators; an adder to add the multiplied values; and a phase extractor to extract a phase component from an output value of the adder and output the phase component as a carrier frequency offset. Therefore, the carrier frequency offset is detected even in case that a pilot signal cannot be employed because of a poor channel environment.

Patent CA-2519735-A1 (CA)
Inventor: URZAIZ EDUARDO
IPC: H04N7/24
Filed: 2004-03-08
Abstract: Data to be transmitted over a network comprise a first part (perhaps audio) which is always to be transmitted and alternative second parts (perhaps video coded at different compression rates) of which one is to be chosen for transmission, depending on the current network capacity. In order to accommodate systems where (owing perhaps to the use of a congestion control mechanism such as TCP) the capacity available is initially undetermined, one firstly begins to transmit just the first part. When the network capacity becomes known (typically by monitoring the performance of the network in transmitting the first part), one of the alternative second parts is chosen and transmission of its commences. If desired this may initially be preferentially to, or to the exclusion of, further transmission of the first part.

Abstract: A method for frame synchronization of a receiver in a wireless communication system wherein data is transmitted in frame units in a multipath environment begins by extracting data samples for a predetermined window size. A training sequence corresponding to a given cell parameter is generated. The data is correlated with the training sequence over different lags to locate the position of the first significant path, which defines the beginning of the frame. The correlated data is accumulated N times for each lag position to produce at least one accumulation vector. A most significant path value and position is determined that is the largest value among the accumulation vectors. A frame synchronization correction value is calculated based on the difference between the first significant path position and a constant called frame offset. The frame synchronization is adjusted based upon the frame synchronization correction value.
