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

摘要

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

SOLUTION: This device comprises 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 comprising a plurality of interleaved words, and a puncturing circuit or repeating circuit for puncturing or repeating bits from 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.
