Optimization design and simplified decoding for short frame CCPM
摘要
Abstract
Considering the demand of burst communications, optimization and simplified decoding for coded GMSK system in short frame was focused on to give an optimum proposal of C2PM system. Simplified demodulator, optimized generation polynomial of the convolution code and matched interleavers were discussed. Simulation results show that for coded GMSK system under AWGN, the performance is better than individual convolution code. Especially when BER is 1×10-5, it performs better than Turbo code and LDPC code with the same frame length, and there is no error floor occur-ring. Finally, complexity analysis shows that the coded GMSK system has lower implementation complexity in compari-son with the commonly used convolution code, Turbo code and LDPC code.关键词
