Space time coding was proposed by combining transmit diversity and coding technology to improve the system performance , such as error bit rate , data rate , and system capacity . in particular , space - time block coding ( stbc ) schemes , proposed originally by alamouti were adopted by the 3g standardization committees as one key technique in 3g wireless systems 将发送分集与编码调制技术相结合,进一步产生了空时编码技术,由于空时编码技术具有优异的抗衰落性能,并且能通过发送分集和接收分集提供高速率、高质量的数据传输,因此它已经成为第三代移动通信技术的重要组成部分,并将继续在下一代移动通信技术的发展中发挥重要作用。
As the distributed wireless system communication becomes a tendency of future public wireless access , the organic combination of distributed antenna and mimo , termed as da - mimo , has become the hotspot of mimo wireless communications research . the signal detection is one of the key techniques in the field of da - mimo system 随着分布无线通信系统成为未来公共无线接口发展的一种新趋势,多入多出与分布式天线技术的有机结合? ?分布mimo成为mimo无线通信领域新的研究热点,分布mimo信号检测是其中的关键技术之一。
This paper can be mainly summarized in to three aspects as follows : 1 . firstly , the paper analyzes the system model of mimo , derive the formulas of channel capacity for the slow flat rayleigh fading channel , analyzes two improtant facts affected the system capacity , and then via the computer simulation we compare the channel capacity between the tranditonal wireless system and mimo system 本文主要做了以下几个方面的工作: 1 .分析了mimo系统的信道模型,理论推导了慢衰落平坦瑞利信道下mimo系统的信道容量公式,简要分析了影响系统容量的两个重要因素并且通过计算机仿真比较了传统无线系统与mimo系统之间的信道容量。
