stbc: space time block coding

Example Sentences:

	1.	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。
	2.	Space - time codes can be divided into tree mainly parts : bell layered space - time architecture ( blast ) , space - time trellis codes ( sttc ) and space - time block codes ( stbc ) . in this paper , we mainly compare the performance of blast and stbc in many aspects , such as design criterion , transmission rate , diversity gain , diversity combining , bit error rate and channel capacity etc . in this paper , we first respectively analysed the instantaneous received symbol energy - to - noise ratio of v _ blast in the diversity combining methods of maximal ratio combining ( mrc ) , equal gain combing ( egc ) and selective combing ( sc ) Mimo技术核心是空时编码( stc ) 。空时编码主要分为三种:分层空时码( blast ) 、空时格码( sttc )和空时块码( stbc ) 。本文主要对分层空时码和空时块码这两种编码方式在设计准则、传输速率、分集增益、接收合并、比特差错率和信道容量等方面进行了较为详尽的研究。
