文章提出了一种最大概率匹配的矢量量化编码算法,它为码书中的每一码字增加一个计数器,统计在编码图象时每个码字的出现的频数,并进行排序;在量化矢量时,根据当前码字出现频数大小依次选择侯选码字,即频数大的码字优先选为候选码字。
This paper proposes a time diversity method,in which a simple transform is taken between the symbols of two channel code words to enable the information of each symbol and the influence of fade to be dispersed into two code words.
该文提出一种利用信道编码,通过在两个码字间进行简单变换,将每个符号的信息分散到两个码字中,同时也将衰落的影响分散到两个码字中,从而获得分集增益。
