Low complexity data detection using fast fourier transform of channel correlation matrix

An is received in a code is the multi-accesses two in communication system time slot of the signal in sharing spectrum. The data signals experienced similar channel response. Similar channel of response estimation. Unit for part and channel estimation response is configured as a data signal channel matrix. Emitting the data vector of the part and channel response matrix input terminals and a Photovoltaic Liye to the decomposes fixing and base. Emitting the data vector are restrained to machine data recovery combined received signal.
