| 摘 要： | 针对基于高斯噪声的无线通信系统无法适应脉冲噪声的情况,以α稳定分布作为脉冲噪声模型,根据模型统计特性,经过理论分析给出了脉冲噪声条件下2ASK的误码特性计算方法,并通过仿真实验验证了该方法的正确性.仿真表明,在混合信噪比较低(MSNR10dB)的情况下脉冲噪声的影响并不明显,接近于高斯噪声,而在较高混合信噪比(MSNR11dB)情况下脉冲噪声使系统的误码率急剧增加,对通信质量造成严重破坏.

| Abstract: | Wireless communication system based on Gauss method is unable to adapt to the impul-sive noise environment.For this situation,after theoretical analysis a new method usingαstable distribution as the impulsive noise model and based on its statistic characteristics for calculating BER of 2ASK communication system is given.The validity of the new BER method is verified through simulation test.The impulsive noise influence is close to the influence of Gauss noise in the case of low MSNR （MSNR〈1 0 dB）.But in the case of high MSNR （MSNR〉1 1 dB）the BER increases rapidly,and the impulsive noise affects badly the quality of wireless communications. |
