摘要

研究了带AWGN和脉冲噪声干扰的四态连续卷积码(SCCC)在瑞利衰落信道上传输的误码率。对于低信噪比(SNR),采用仿真结果,而对于高信噪比,采用平均上界。结果表明,与未编码的情况相比,使用SCCC时,瑞利衰落并不那么有害。与非衰落情况类似,脉冲噪声干扰在高信噪比(SJR)时更有效,而信道信息在低信噪比时更有用

Performance of BPSK serially concatenated convolutional codes in the presence of pulsed-noise jamming and Raleigh fading
In this paper, the bit error rate (BER) of BPSK with a four-state serially concatenated convolutional code (SCCC) with AWGN and pulsed-noise jamming transmitted over Rayleigh fading channels is examined. For low signal-to-noise ratios (SNR), simulation results are used, while for higher signal-to-noise ratios, an average upper bound is developed. Results show that Rayleigh fading is not as detrimental when a SCCC is used as compared to the uncoded case. Similar to the non-fading case, pulsed-noise jamming is more effective at higher signal-to-jamming noise ratios (SJR), while channel information is more useful at lower SNRs
