sttc meaning in Chinese
空时格形码
Examples
- When the number of the antennae is not changed , the complexity of sttc decoding would increase on index with the acceleration of the transmission rate
空时格形码在天线数目固定时,译码复杂度随发射速率的增大呈指数增加。 - Then the performance for sttc in multipath and time - dispersive fading channels is derived . in chapter 5 , space - time block coding ( stbc ) is studied
研究了空时格状编码在多路径和时间色散的衰落信道中的性能，得到它的性能限。 - In chapter 4 , space - time trellis coding ( sttc ) is studied . an exact pairwise error probability is derived for space - time codes operating over rayleigh fading channels
在第四章中，研究了空时格状编码的问题，推出了误码概率的确切表达式。 - However , stbc overcomes the limitation of sttc that its decoding is very complexly . it makes use of ml decoding arithmetic which possesses orthogonal designs
空时分组码则克服了空时格形码译码过于复杂的缺陷,它利用具有正交设计的最大似然译码算法实现。 - 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。
