面向联合编码的FTN系统的简化均衡算法
Simplified Equalization Algorithm for FTN Systems Oriented Towards Joint Coding
摘要
Abstract
In order to solve the problem of inter symbol interference introduced by compressed time-domain factor transmission in faster-than-Nyquist(FTN)systems,an FTN system based on joint source channel cod-ing(JSCC)is proposed,and a simplified equalization algorithm,S-M-BCJR,based on the Ungerboeck model is designed.By introducing prior probability information of the source and combining channel shortening tech-niques with a state selection mechanism,the proposed algorithm significantly reduces computational complexity while maintaining excellent detection performance..Simulation results show that when using binary phase shift keying(BPSK)modulation,the complexity of the proposed algorithm is reduced by about 50%compared to the standard BCJR algorithm,with nearly equivalent bit error rate performance.关键词
