Abstract:

In order to improve the comprehensive performance of the decoding algorithm for the error correcting code, a new genetic probability decoding (GPD) algorithm based on genetic algorithm is proposed. This GPD algorithm can further offset the quantification error of the hard decision by applying the additional information in the received sequence with non-quantification, and then restore the maximal likelihood transmission code word. Analysis of the GPD algorithm shows it wont be affected by the number of code symbols, the decoding complexity is relatively lower and the optimization fast decoding can be achieved. Simulation shows that the proposed GPD algorithm has a better decoding correction-error performance.
