Title:
【発明の名称】(N-1)ビット情報語系列をNビット・チャネル語系列に符号化する符号化装置およびNビット・チャネル語系列を(N-1)ビット情報語系列に複号する複号装置
Document Type and Number:
Japanese Patent JP3425152
Kind Code:
B2
Abstract:
Encoding arrangement for encoding a sequence of (n-1)bit information words into a sequence of n-bit channel words, and a decoding arrangement for decoding a sequence of n-bit channel words into a sequence of (n-1)-bit information words. The encoding arrangement comprises input means for receiving the information words, converter means for converting the (n-1)-bit information words into n-bit channel words and output means for supplying the channel words. The converter means comprises weight vector coefficient supply means for supplying a weight vector w, the weight vector having n weight vector coefficients wi, where i is an integer running from 1 to n and the weight vector coefficients being in the form of (n-1)-bit binary words, and calculation means for carrying out a calculation using an information word so as to obtain a channel word. The weight vector coefficient supply means is adapted to supply only p bits of a weight vector coefficient wi, the remaining n-1-p bits of the (n-1)-bit weight vector coefficient word being 'zeroes' to be added before or after the p-bit binary word or before and after the p-bit binary word so as to obtain said weight vector coefficient, and that p is an integer smaller than n-1.
