Multiple-Input Multiple-Output (MIMO) systems, employing multiple antennas at both the transmitter and the receiver, can achieve remarkably high spectral efficiencies in rich scattering environments. As a result, the design of high data-rate MIMO communication systems has attracted a significant interest. A prime example is the BLAST (Bell LAboratories layered Space Time) architecture, which has been proposed to exploit the potentially enormous MIMO link capacity. In spatial multiplexing systems, a fundamental receiver function is the detection of transmitted data symbols. The optimal Maximum Likelihood Detector (MLD) minimizes the error probability.
