-
Then the performance for sttc in multipath and time - dispersive fading channels is derived. in chapter 5, space - time block coding ( stbc ) is studied
研究了空時格狀編碼在多路徑和時間色散的衰落通道中的性能，得到它的性能限。 -
We propose the joint filterbank precoders and decision feedback equalizers structure at first, by which the dispersive channel is equivallent into parallel independent flat fading subchannels such that the diversity gain of the receiver is increased. then we adopt the discrete - time ( dt ) canonical model to convert the problem of blind signal processing of tv dispersive channels into processing the time - invariant multi - channels model blindly, and discuss the problem of blind equalization and identification of tv dispersive channels based on this new model
第一種是採用濾波器組聯合均衡方法將色散通道等價為一組獨立的平坦衰落子通道，以提高接收機的分集增益；另外一種是提出採用離散正則模型將時變色散通道的盲信號處理轉化為時不變多通道模型的盲信號處理，並針對該模型對時變色散通道的盲均衡與盲辨識方法進行了詳細討論。 -
This method can convert the dispersive channels into independent flat fading subchannels, so that it increase the diversity gain of the receiver and outperform that of the original paper as for the ber performance and maximum mutual information while maintaining all the advantages of it. in chapter 4, the models of the tv dispersive channels are reviewed in signal processing perspective
在第四章中，作者對時變色散通道的信號處理模型進行了研究，提出了離散正則模型的概念，對其進行了詳細的討論，並利用多采樣率理論將該模型推廣到一般的時變色散通道。
