那么,接收到的向量,可以不相互干扰地分解出这两个坐标: 则两边同时乘以 有: 同理,若则两边同时乘以 有: 多优美的结果呀! 我们再来分析一下接收到的信号的信噪比情况,因为接收到的信号的信噪比,直接影响误码率。因为两个发送的符号,在公式上是完全雷同的,分析一个即可。我们用向量的形式来分析。 若对下式把 ...
发射分集 Space Time Block Coding (STBC) - 哔哩哔哩 (bilibili.com) 其中有一步公式如下: 首先,需要考虑的是平均情况,即应该考虑数学期望: 需要对最后分子部分进行重新推导: 继续 继续 公式(3) 中,考虑数学期望的,即在大数据量情况下的平均,考虑各个随机变量的独立性以及均值为 0 则原文章中的公式就为:...
The combination of space-time block coding (STBC) and direct-sequence code division multiple access (DS-CDMA) has the potential to increase the performance of multiple users in a cellular environment. However, if not carefully designed, the resulting communication scheme suffers from increased multi...

Space-time block coding (STBC) is an effective transmit diversity scheme. It was presented previously by in terms of coding and decoding by Alamouti (see IEEE J. Select. Areas Commun., vol.16, no.8, p.1451-58, 1998) and by Tarokh, Jafarkhani and Calderbank (see IEEE Trans. Inform....
Space-time block coding (STBC) is a promising candidate for the next generation cellular communications standard, especially in the downlink system. In the downlink WCDMA system, multiple access interference (MAI), which impairs performance of the receiver, can be eliminated by channel chip level eq...
