A Dual-Path 4-Phase Nonuniform Wideband Receiver With Digital MMSE Harmonic Rejection Equalizer

This paper presents a dual-path nonuniform blocker tolerant wideband receiver that employs digital harmonic rejection to suppress local oscillator (LO) harmonic interferers. The proposed receiver performs harmonic rejection of any LO harmonic including seventh and ninth using only four uniformly spaced clocks each with 25% duty cycle. An adaptive minimum mean-squared error (MMSE) harmonic rejectio...
