摘要
基于高阶累积量的信号处理理论 ,提出了一种快速、简便且无偏估计的方法对多频信号进行有效的检测。这种方法与通常在电话网信号中所采用的基于相关的检测方法相比 ,具有很好的抗噪声性能 ,且能满足实时处理的要求 。
Based on signal processing theory about high order cumulants (HOC), a fast, inexpensive and unbiased cumulants estimation approach is proposed for the detection of multi frequency signals between offices connected to telephone networks. The performance of suppressing noise and practicality of the approach based on HOC is better than that of approach based on autocorrelation.
