摘要： Iterative detection for a MIMO (multiple-input, multiple-output) wireless communications system uses multiple stages for interference cancellation refinements. Detection is determined by maximizing signal to noise plus interference ratios. Equalization matrix updating uses a matrix-inversion-free recursion. For P transmitter antennas and Q receiver antennas, the soft symbol vector estimates are z=Fr−Gshard with F a P×Q IMMSE detector, r the received Q vector, and G a P×P interference canceller with shard hard decisions of prior symbols and iterations.
