A METHOD OF RECEIVING A SIGNAL COMPRISED OF A GROUP OF SPREAD SPECTRUM CALL SIGNALS SHARING A COMMON FREQUENCY BAND

Abstract An integrated search processor used in a m dem for a spread spc, _rum communications system buffers receive samples and utilizes a time sliced transform processor operating on successive Offsets from the buffer. The search processor autonomously steps through a search as configured by a microprocessor specified search parameter set, which can include the group of antennas to search over, the starting offset and width of the search window to search over, and the number of Walsh symbols to accumulate results at each offset. The search processor calculates the correlation energy at each offset, and presents a summary report of the best paths found in the search to use for demodulation element reassignment. The search is done in a linear fashion independent of the probability that a signal being searched for was transmitted at any given tinge.
