Wiener Filter Aided Second-order Cyclostationary Feature Detection of Mixed Signals for Higher Recognition Precision

The cyclostationary analysis has been used to detect mixed signals for recognizing signals. However, the noises existent in signals lower the recognition precision. In this paper, we propose to utilize the Wiener filter to reduce the noise variance, thereby improving the mixed signal detection precision. In our de-sign, we first utilize the Wiener filter to suppress the noise existent in received ...
