Wideband Channel Tracking with Quantization Distortion

Outdated channel state information (CSI) at the base station (BS) can lead to significant performance degradation, making channel tracking crucial. In this paper, we propose a channel tracking algorithm that leverages the Bussgang decomposition and the Kalman filter to mitigate quantization distortion. Simulations demonstrate the effectiveness of the proposed algorithm under conditions of severe quantization distortion.
