Patent CA-2142092-C (CA)
Inventor: DAVIS MARK FRANKLIN
IPC: H04S3/02
Filed: 1993-10-08
Granted: 2004-09-21
Abstract: In a system in which a low-bit rate encoder and decoder carries matrixed audio signals, an adaptive rematrix rematrixes matrixed signals from an unmodified 4:2 matrix encoder to separate and isolate quiet components from loud ones, thereby avoiding the corruption of quiet signals with the low-bit-rate coding quantization noise of loud signals. The decoder is similarly equipped with a rematrix, which tracks the encoder rematrix and restores the signals to the form required by the unmodified 2:4 matrix decoder. The encoder adaptive rematrix selects the matrix output signals or the amplitude weighted sum and difference of the matrix output signals. The choice of whether the matrix output signals or the sum and difference of the matrix output signals are selected is based on a determination of which results in fewer undesirable artifacts when the output audio signals are recovered in the decoder. The adaptive rematrix may operate on frequency component representations of signals rather than the time-domain signals themselves.

Patent CA-2202621-C (CA)
Inventor: HARMS BRIAN
IPC: H04B1/69
Filed: 1996-06-28
Granted: 2005-11-15
Abstract: A technique for using energy received by subscriber units over multiple orthogonal channels within a spread spectrum communication system to acquire signal timing by controlling signal amplitude integration intervals used in detecting such timing. Received signals (10, 14, 18) are despread (40, 60) and respective amplitues coherently integrated (42, 44, 46, 62) over periods that are divisible by factors of two into the length of Walsh functions used to generate orthogonal signal channels.    Non-coherent combinations of the results of this integration are subsequently formed (68) over periods that commence and terminate on Walsh function boundaries, and used to determine when a correct time offset has been selected for despreading signals. Additional advantages are realized by assigning signals that consistently provide a higher energy content such as paging, synchronization, and most frequently assigned traffic channels to specific orthogonal channels within the communication system. In exemplary embodiments, Welsh functions of length 128 are used as channelizing codes and a pilot signal is assigned to channel 0. This results in traffic channels or paging and synchronization functions being assigned to channel (64) when the integration periods are (64) chips long, and to channels (32, 64 and 96) when the periods are (32) chips long. In this manner, additional energy is available during the integration process for use in determining when correct signal acquisition timing offsets have been selected, without the use of additional hardware.
