物理层网络编码(PNC)的基本思想是叠加信号以提高吞吐量。目前的研究主要集中在AWGN或Rayleigh信道上的PNC，没有考虑突发脉冲。本文旨在评估经典PNC在考虑高斯噪声和突发脉冲联合影响的混合信道上的误码率性能。此外，本文还探讨了在混合信道中使用RS码来改善PNC的误码率性能。仿真结果表明，突发脉冲会使误码率显著下降，而RS码能够补偿显著的误码率性能下降。
The essential idea behind physical-layer network coding (PNC) is to superimpose signals so as to improve throughput. Current studies focus mainly on PNC over the AWGN or Rayleigh channels without consideration of burst pulses. This paper aims to evaluate the bit error rate (BER) performance of classical PNC, over a mixed channel that considers the combined effects of Gaussian noise and burst pulses. Besides, this paper explores the use of the Reed-Solomon (RS) codes to improve the BER performance of PNC over the mixed channel. Simulation results show that burst pulses deteriorate the BER significantly, and the RS codes are able to compensate for substantial BER performance degradation.
