Abstract

In this paper, the STBC (Space-Time Block Codes) transmission technique is used in order to evaluate the link availability and transmission quality of multi antenna systems that operate under various channel conditions. The propagation channel follows the IEEE 802.11n specifications. The influence of the diversity order and the spatial correlation is investigated in terms of error performance and throughput. The efficient use of the space and the power resources leads to significant improvement in the link reliability, if channel state is available at the transmission. The throughput enhancement of a 2×2 MIMO system relatively to the basic SISO (Single Input Single Output) mode is evaluated considering a fix antennas separation and different channel models.
