The Physical Layer Design for MIMO Wireless Communications System

In this article, we address the issue of physical layer design of MIMO wireless communication system. First, we analysis the capacity of MIMO system in a limited space, then investigate the capacity varied with the number of antenna and SNR in SIMO, MISO, MIMO system. Second, we explore the design of antennas assignment and space-time coding based on the optimizing trade-off diversity gains and multiplex gains. Third, we study the criteria of power allocation in antennas for different channel conditions or interference. Finally, a physical layer design algorithm for MIMO wireless communication system is present.
