摘要

This contribution proposes a coding procedure for the binary frequency shift keying (FSK) modulation, to combat the severe narrowband power line communication (NB-PLC) channel constraints, in particular, the impulse noise (IN). The coding procedure is composed of a short 2-error correcting Bose-Chaudhuri-Hocquenghem (BCH) block code concatenated with a permutation code (PC) with a minimum distance of dmin = 2. The parameters of the BCH codes are optimized to delete the error floor (EF) effect caused by the IN. Three different decision techniques are compared, which are FSK select largest (FSK/SL), FSK soft decision (FSK/SD), and spread FSK (SFSK). The proposed concatenated codes scheme using FSK/SL gives the same performance results achieved by FSK/SD while keeping low computational complexity. The system removes the EF and gives a Bit Error Rate (BER) = 10-5 at Signal-to-Noise Ratio (SNR) = 15.6 dB under realistic PLC channel transfer function and IN conditions, gaining more than 10 dB over the PC only system.

BCH代码的参数经过优化，可删除由IN引起的错误楼层（EF）效果。比较了三种不同的判定技术，这是FSK选择最大（FSK / SL），FSK软判决（FSK / SD）和扩展FSK（SFSK）。使用FSK / SL的所提出的连接代码方案提供了通过FSK / SD实现的相同的性能结果，同时保持低计算复杂性。系统删除EF并给出误码率（BER）= 10 -5 在现实的PLC通道传输功能和条件下，在遥控率（SNR）= 15.6 dB下，在PC上获得超过10 dB的系统。
