Dynamic System Performance of SISO, MISO and MIMO Alamouti Schemes

Free registration required

Executive Summary

MIMO systems have been deeply investigated during the last years. They have been proven to achieve better performance in terms of capacity through the multiplexing gain and in terms of reliability through to the diversity gain. Tradeoffs between these two promised gains have been established. Space-time codes were introduced as a technique permitting to achieve this tradeoff. In this paper, the Alamouti code was proposed as a space-time code meeting the diversity multiplexing tradeoff for a 2 1 MISO system. Many other techniques have been proposed to exploit antennas diversity.
