摘要: K data signals are transmitted over a shared spectrum in code division access communication system. A combined signal is received and sampled the (48). The has channel response matrix produced (49) using codes impulse responses of signals. block column correlation determined (50). Each entry by (51). At each frequency point k, taking Fourier transform entries (52). An inverse multiplied to result Alternately, forward substitution (53) backward (54) can be used solve recover from (55).
