Abstract

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.
不同技术下多天线系统的性能分析
在带宽和功率等可用资源的限制下,无线通信系统对可靠的通信、更高的容量、灵活的数据速率和广泛的应用需求越来越高。同时,采用空时编码(STC)实现多输入多输出(MIMO)系统,实现无线通信的最大分集、最大编码增益和最大吞吐量。本文将几种常用技术应用于MIMO系统,并对其性能进行了研究。研究了基于瑞利平衰落信道的非编码系统的MIMO系统。我们还研究和比较了使用不同信道编码技术的MIMO系统。最后,对采用各种交错和穿刺方案的MIMO系统性能进行了分析,并证明了其性能有一定的提高。
