Interference-resistant LPTV-MMSE equalization

The problem of recovering a digital communication signal distorted by a linear time-invariant channel and contaminated by severe co-channel or adjacent-channel digital interference is addressed in this paper. The proposed linear periodically time-varying (LPTV) receiver jointly performs channel equalization and interference suppression, without requiring explicit knowledge or estimation of the interfering channel. Simulation results confirm the effectiveness of the proposed technique, whose performance exhibit a remarkable robustness with respect to varying interference power level.
