参数估计器的偏差补偿 - Performance analysis of space - time code for nakagami fading channel
信道中空时分组码的性能分析 - Moreover , new close - form ber expressions of mqam and mpsk in nakagami - / ? ? fading channel are derived , which include the known analytical results as a special case
本文还导出了nakagami - m衰落信道下mqam和mpsk调制方式新的误比特率表达式，该表达式可以使现有文献的分析结果西南交通大学博士研究生学位论文第v页成为其特例。 - Under rayleigh fading channel , we also simulated and compared ber in siso 、 simo and mimo systems . secondly , based on careful study the ber and the channel capacity under white noise channel under mpsk modulation when the channel is rayleigh fading , we duduced the expressions of stbc ’ s ber and channel capacity under rice and nakagami fading . and also analysed the performances through numerical simulation using matlab to testify the exactitude of the dudeced expressions . finally , there exists an error floor of stbc through studying on its performance on time - selectiv fading channel . we analysed the reason and proposed two new decode combination scheme to eliminated the error floor and the performance of stbc on time - selective fading channel is improved . and also compared the two scheme ’ s complication and snr gain
这些结果大部分是闭式结果,能比较准确地衡量空时块码的性能,并对不同衰落的性能做了相互比较,其结果对空时块码的实际应用具有一定的指导意义。实际的信道是时变的,分析了空时块码在时间选择性衰落信道中产生误差地板效应的主要原因是存在码间干扰( isi ) ,在此基础上提出了两种能消除误差地板效应的译码合并方案,并对这两种方案的复杂度和信噪比增益进行了比较。
