Methods of temporal signal processing in an adaptive transversal filter

Journal of Radio Electronics
A single-channel adaptive transversal filter based on a multi-tap delay line is considered. It is assumed that the filter is affected by broadband interference, which is a rather complicated case in practice. This problem is typical for radar systems and electronic warfare systems. Two methods of digital signal processing are proposed. The first method
