摘要

本文研究了多输入多输出(MIMO)系统中的正交空时分组码(OSTBC)。利用天线选择技术(AST)在威布尔-伽玛衰落(WGF)信道上评估MIMO通信系统的性能。在降低硬件复杂度的同时，利用发送端信道状态信息可以提高系统容量和错误率。AST中的CSIT用于MIMO系统在WGF信道上的OSTBC，以提高系统的误码率。讨论了在威布尔衰落参数和伽马衰落参数下信噪比性能的改进。本文推导了不同天线数量下的最优和次优AST分析，并分析了信道的容量改进。

Sub-optimal antenna selection technique over Weibull-Gamma fading channel for MIMO communication systems

In this paper, the orthogonal space-time block code (OSTBC) of the multi-input multi-output (MIMO) system is considered. The performance of a MIMO communication system is assessed using antenna selection techniques (AST) over the Weibull-Gamma fading (WGF) channel. The channel state information on the transmitter side (CSIT) can be utilised to improve the system capacity and error rate at the same time with reduced complexity of the hardware. The CSIT in AST is used for OSTBC of the MIMO system over the WGF channel to improve the bit-error rate (BER) of the system. The SNR performance improvement is discussed over Weibull and gamma fading parameters. In this paper, both optimal and suboptimal AST analysis is derived for various numbers of antennas and capacity improvement of the channel is analysed.

期刊介绍： The explosive growth of wide-area cellular systems and local area wireless networks which promise to make integrated networks a reality, and the development of "wearable" computers and the emergence of "pervasive" computing paradigm, are just the beginning of "The Wireless and Mobile Revolution". The realisation of wireless connectivity is bringing fundamental changes to telecommunications and computing and profoundly affects the way we compute, communicate, and interact. It provides fully distributed and ubiquitous mobile computing and communications, thus bringing an end to the tyranny of geography.
