Blind adaptive FRESH filtering for signal extraction
Jian‐Kang Zhang, Kon Max Wong, Zhongqiang Luo, P.C. Ching · IEEE Transactions on Signal Processing · 1999
A blind adaptive method called the BA-FRESH (optimum frequency-shift) filtering technique is proposed and its convergence analyzed. The BA-FRESH filter does not require training signals nor knowledge of the statistics of the desired signal. It is capable of separating desired signals from spectrally overlapping interference by knowing only the cycle frequencies of the signals.
