Abstract | A novel concatenated coding system for both narrowband and broadband power line communications (NB-PLC andBB-PLC) is proposed. The order of the inner and the outer codes switches from the G3-PLC standard and the interleaver iseliminated. The Error-and-erasure decoder (EED) is selected as the Reed-Solomon inner code is because the impulsive noisesclearly mark the erasure positions with a threshold-based algorithm. The nonbinary convolutional outer code with vectorsymbol decoding (VSD) can correct longer burst errors. The results show that for BB-PLC, the bit error rate (BER) of RS (63,51)error-only (ED) with VSD is 1.5?10-5 and of EED-VSD is 9.0?10-9 at Eb/No 26 dB. For NB-PLC, the BER of ED-VSD is 7.9?10-5 andof EED-VSD is 2.2?10-8 at Eb/No 16 dB. Therefore, BER of EED-VSD is three to four orders of magnitude lower than ED-VSD.Moreover, NB-PLC reaches the desired BER around 10-7 at about 10 dB lower Eb/No than BB-PLC. |
