Scientific development brings great change to our daily life, in this age of information, there is increasing need not only for speed, but also for accuracy in the storage, retrieval, and transmission of date, and the advancement of communication technique also give profound influence to our civilization.
People's demands for the high-speed data transmission promote the development of PCS. As we all known, in the modern communication system, error-correction code is a fundamental technique which can guarantees reliable communication .The life transformation rate is became more and more fast, so more better channel coding and decoding ways are needed, so as to improve extremely communication efficiency and quality.
In this paper we introduced the information theory then draws out the fundamental concept of the coding technology, and introduced the BCH coding principle and the decoding algorithm with emphasis. The Markov model three states are used for the probability model in the digital mobile communication channel with long burst error. By means of a simplified method and by use of the error-codes generate by the parameters of the model. At last, we complete the simulation and analysis of BCH error code, the analogue result indicated that, with the Markov model three states express the motion channel has a higher precision, and the BCH code has the better error correction performance.
