We consider the problem of detecting a vector of symbols that is being transmitted over a fading multiple–input multiple–output (MIMO) channel, where each symbol is an M–th root of unity for some fixed M ≥ 2. Although the symbol vector that minimizes the error probability can be found by the so–calledmaximum–likelihood (ML) detector, its computation is… (More)
