摘要: A plurality of communication bursts are transmitted substantially simultaneously in a time slot division duplex/code multiple access system. The system has maximum number K midamble shifts. Each burst an assigned midamble. is shifted version basic code having period P. combined signal received. includes received each the burst's midambles. P by square circulant matrix constructed including channel response determined for shifts using prime factor algorithm (PFA) discrete Fourier transform (DFT) algorithm, and matrix. PFA DFT stages. stage inputs.
