| 摘 要： | 针对现实中多数信道为脉冲噪声环境的特点,以α稳定分布和信道编码理论为基础,并以α稳定分布噪声为脉冲噪声模型,运用M atlab软件研究了脉冲噪声环境下编码信道的抗噪声性能。研究结果表明,SNR较大时脉冲噪声对编码信道所造成的误码影响远大于高斯噪声所造成的误码影响。

| Abstract: | Complied with the reality that the majority of the channels are in the impulse noise environment, the anti-noise performance of the coding channel based on the theory of a-stable distribution and coding channel is researched here by Matlab. The noises which follow the or-stable distribution are used as the impulse noises in this paper. Studies show that, the alpha noises make much bigger influence than the Gauss noises to the coding channel when the SNR is bigger. |
