A beam design method based on signal-to-leakage-plusnoise ratio (SLNR) has been recently proposed as an effective scheme for multiuser multiple-input multipleoutput downlink channels. It is shown that its solution, which maximizes the SLNR at a trans

A MIMO detection algorithm utilizing poly- diagonalization and tail-biting trellis is proposed. Linear MIMO detection, such as zero-forcing or minimum mean squared error (MMSE) equalization, is basically a channel diagonalization technique, where int
