摘要 基于空时分组码的发射分集技术既能很大程度地改善通信系统的误码性能,又不需要占用额外的频谱资源,还具有良好的频带利用率,是近年来的研究热点之一。在简单介绍了空时分组码的工作原理的基础上,对空时分组码与最大比接收分集合成作了比较,提出了一种空时发射分集实现的方案,此方案的优点使其更能适合未来移动通信的发展。 Since the scheme of transmit diversity based on space-time block code can not only reduce the BER of system greatly, but also does not require any bandwidth expansion, it is a hotspot in mobile communication system. This paper introduces the principle of space-time block code briefly and discusses some problems encountered in realization.
