Abstract
According to various embodiments, apparatus and methods disclosed herein may be implemented in a digital communication (wired or wireless) receiver, and relate to minimizing noise in an estimated channel frequency response at the receiver for the purposes of channel equalization. The disclosed apparatus and methods may include determining a channel impulse response based on an estimated channel frequency response. The estimated channel frequency response, the channel impulse response, or both may include noise. An impulse response mask may be determined based on the channel impulse response, and further applied to the channel impulse response to obtain a noise-reduced channel impulse response, which may be Fourier transformed to obtain a noise-reduced channel frequency response.
