Abstract

A channel coding method of variable length information using block code is disclosed. A method for channel-coding information bits using a code generation matrix including 20 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having ''A'' length using basis sequences having 20-bit length corresponding to columns of the code generation matrix. If ''A'' is 10, individual basis sequences of the code generation matrix correspond to column-directional sequences of a specific matrix composed of 20 rows and 10 columns. The specific matrixis made from 20 rows of the (32, 10) code matrix used for TFCI coding were selected.

Description

technical field [0001] The present invention relates to a coding method of a mobile communication system, and more particularly, to a method of efficiently performing a channel coding process on variable-length information using a block code. Background technique [0002] For the convenience of description and better understanding of the present invention, some concepts required by the present invention will be specifically introduced from several basic coding theories below. [0003] Generally, [n, k, d] is used to represent the universal binary error correction code, where "n" is the number of bits of the encoded codeword, "k" is the number of information bits generated before the encoding process, and "d " is the minimum distance between codewords. In this case, only binary codes are considered for the above-mentioned binary error correcting codes, so that 2n is used to denote the number of possible codeword points in the code space, and 2k is used to denote the total nu...
