Multiple - antenna techniques have been recognized as a key technology for modern wireless communications, which provide new degrees of freedom for achieving higher data rates and smaller error probabilities by exploiting the previously unused spatial domain. In particular, higher data rates can be achieved via spatial multiplexing techniques such as the V - BLAST (Vertical Bell Laboratories LAyered Space-Time) scheme. These techniques simultaneously transmit independent information messages over multiple transmit - antennas to achieve a spatial multiplexing gain. However, the price to be paid for this increase in the data rate is additional hardware and signal processing complexity.
