one counter is added for every codeword in the codebook, it counters the times that the codeword emerged in the encoding image.
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.
