| 摘 要： | 根据谱相关的相关理论,提出了利用谱相关来实现低信噪比扩频信号的循环平稳特征提取方法,采用Monte Carlo方法进行计算机仿真,谱相关方法不仅在较低的信噪比条件下能很好地提取循环平稳特性,而且大大地降低了计算量。

| Abstract: | According to the correlative theory and application of spectral correlation, a method to detect the cyclic-stabilization characteristic of SD/SS by cyclic-spectrum is proposed. By the Monte-Carlo method, the result of simulation shows that the spectral correlation can work well on the lower SNR and greatly decreases the calculation quantity. |
