Performance Evaluation of STBC MIMO Systems with Linear Precoding

Abstract

It is known that transmit channel side information (CSIT) is used to enhance the performance of space-time block codes based multi-antenna communication links. In this paper, we analyze how transmission algorithms can be adapted to the channel condition based on the degree of the available CSIT and the system diversity order. The precoding design criterion considered is minimizing the average pairwise error probability. The analyzed parameters are the bit error rate (BER) and the link throughput.
