One Reduced-Rank Blind Fresh Filter for Spectral Overlapping Interference Signal Extraction and DSP Implementation

In this paper we begin with reviewing the concept of cyclostationarity and then illustrate that a conventional blind FRESH filter is not suitable to apply in project because the computational complexity is very high. A reduced-rank method was developed as [5][6] which is based on MSWF. Then we constructed a test model to verify the algorithm performance which implements in DSP. The Matlab simulation and the statistical outcome of DSP indicate that the method could extract spectral overlapping interference signal.
