摘　　要：在短波干扰信道下,对采用限幅度量的动态频谱抗干扰系统比特误码率(BER)进行理论分析。以Odenwalder(2,1,7)卷积码作为纠错编码,给出系统的BER上界,并进行仿真验证。结果表明,采用纠错编码及抗干扰译码度量后,系统的抗干扰性能提升可达10dB以上。Bit error rate(BER)performance of the dynamic spectrum anti-jamming(DSAJ)systems using clipped decoding metric is analyzed under a high-frequency(HF)interference channel.BER upperbound is deduced and validated via simulation with Odenwalder(2,1,7)convolutional code as the error correction coding scheme.Results show that the antijamming capability of DSAJ systems improves more than 10 dB with error correction coding and anti-jamming decoding metric being used.
