摘要
研究了高阶统计量(主要是三阶累积量)在信号检测中的应用,探讨了信号检测的高阶累积量算法.利用高斯噪声的高阶累积量的零均值特性,用计算机对SNR=20 dB和SNR=0 dB的输入信号进行模拟仿真,并将检测结果与原始信号进行比较,从结果上看执行效果较好.
This paper studies the application of higher-ordered statistics （ mainly third-order accumulated values） in signal detection. The algorithm of signal detection is explored using higher-order accumulated values. By use of the zero mean characteristic of higher-order accumulated values of Gauss noise, simulations are conducted with the input signals of SNR = 20dB and SNR = 0dB in computer, and the results are compared with the original signals, indicating that the new method is better.
