| 摘 要： | 为了分析高斯白噪信道中线性分组码的译码性能,提出了采用低信噪比时数值仿真和高信噪比时理论估算相结合的方法来计算误码率,从而快速准确地获取整个信噪比范围内的译码性能曲线.试验结果表明,该方法得到的误码率与实际误码率一致.

| Abstract: | In order to analyze the decoding performance of linear block codes,a new method is proposed in this paper. The decoding performance plot can be gotten quickly and precisely within a wide SNR range by using computer emulation when SNR is low and theoretical estimation when SNR is high. Simulation results show advantage of the proposed method over conventional methods is much faster speed with little difference of the real decoding performance. |
