Computationally efficient equalization implementation for known channel. The equalizer works in the frequency domain.

This approach is based upon a minimum mean-square error (MMSE) formulation in which the pulse compression filter for each individual range cell is adaptively estimated from the received signal in order to mitigate the masking interference resulting from matched filtering in the vicinity of large targets.
