Method of transmitting data using repetition coding

摘要

A data transmitting method using repetitive coding in a wireless communication system is provided to improve the performance of the channel decoding by uniformizing a probability distribution of an input value of a channel decoder. An original codeword is generated by channel-coding information bits. At least one repetition codeword repeating the original codeword is interleaved. The codeword interleaved with the original codeword is transmitted. The original codeword and the repetition codeword are mapped to the plurality of data symbols. The bits of the repetition codeword corresponding to the bits of the original codeword are interleaved to be mapped to the different data symbol. The bits of the repetition codeword corresponding to the bits of the original codeword are interleaved to belong in the bit group with different error generation probability.
