摘要
简要阐述了多符号检测(MSD)技术和TURBO乘积码(TPC)技术,对这两项技术在PCM-FM遥测系统中的应用进行仿真和工程实现。测试结果表明,在误码率为1×10-7的条件下,应用这两项技术的PCM-FM系统相比原系统可获得近9dB的信道增益。
This paper presents the basic principles of multi-symbol-detector(MSD) and turbo product codes(TPC),and gives the performance curves from the simulation and experiment.The results show that this combination can improve the detection performance by nearly 9 dB relative to conventional PCM-FM systems.
