Performance analysis of multiple antenna systems within different techniques

Wireless communication systems have ever increasing demand for reliable communication, higher capacity, flexible data rate and wide variety of applications under the constraint of available resources like bandwidth and power. Meanwhile, multiple input multiple output (MIMO) system is implemented using space-time codes (STC) to achieve maximum diversity, maximum coding gain and the highest possible throughput for wireless communications. In this paper, we applied several popular techniques to MIMO system and study its performance. We explored the MIMO system over an un-coded system using Rayleigh flat fading channel. We also studied and compared the MIMO system using different channel coding techniques. Finally, the performance of MIMO system applying various interleaving and puncturing schemes is analyzed and proved to gain some improvement.
