maximum mutual information ( mmi ) is the most popular method in vsb . in this thesis we analyse its characters . it shows high performance in case of adding different noise to the floating image 在基于體素的方法中,最大化互信息法是目前研究的熱點(diǎn),本文對最大互信息法的性能做了詳細(xì)的分析。
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,作者對時變色散信道的信號處理模型進(jìn)行了研究,提出了離散正則模型的概念,對其進(jìn)行了詳細(xì)的討論,并利用多采樣率理論將該模型推廣到一般的時變色散信道。
