Executive Summary

Conventional SISO (Single Input Single Output) systems are limited by the multipath propagation and interference, so they cannot satisfy the demand for high data rates and better quality systems. The benefits of MIMO (Multiple Input Multiple Output) techniques are well established: linear growth in transmission rate with the minimum number of antennas, enhance in the link reliability and coverage, efficient use of bandwidth, are all obtained without additional radio resource requirements, like bandwidth or more transmit power. The only demand is that the receiver has perfect knowledge of the channel state information (CSIR - Channel State Information at the Receiver).
