Regularization Method on Complex Signals De-noising
Xiong Wang · Modern Radar · 2004
Aiming at complex signal, a novel de-noising method based on regularization is presented. Based on parameter selection of Tikhonov regularization, automatic optimal regularization parameter selection method is proposed. It can directly deal with complex signal and differs very much from most of the conventional complex signal de-noising methods. Simulation results show that this method behaves well in signal de-noising and efficiently preserves the important feature of the signal at the same time. [
