Abstract

PURPOSE:To encode data blocks in order and to make it possible to apply it for the high speed communication system by executing the encoding processing keeping pace with the lapse of time by use of the encoding unit. CONSTITUTION:The encoder is divided into several encoding units 6-0-6-3, to which the block information of the initial value consisting of the code key and the code basic data is set. And each encoding unit 6 executes the encoding processing 7 keeping pace with the lapse of time in order that the i-th block, the i+1-th block,... of the data stream can be encoded by means of each encoding unit 6, and also the i+n-th block, the i+n+1-th block,... of the data stream can be encoded by means of each encoding unit 6. Thus elevation of the processing speed can be attained.
