ERROR CORRECTION CIRCUIT, AND TRANSMISSION SYSTEM INCLUDING INTERLEAVER, AND PUNCTURING OR REPEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a coding device for adjusting a signal rate in a wireless communication system.

SOLUTION: A coding device includes a coding circuit for converting a digital input into a coded output having a greater number of bits than the input, an interleaving circuit for combining a plurality of words of the coded output and producing therefrom a data block having a plurality of the interleaved words, and a puncturing circuit or repeating circuit for puncturing or repeating bits form the data block. The puncturing or repeating circuit uses a deleting or repeating pattern to provide data words for transmission during respective frames of a transmission channel. The deleting or repeating pattern is selected depending upon the characteristics of the coding circuit and of the interleaving circuit.
