Learning based Channel Estimation and Phase Noise Compensation in Doubly-Selective Channels
Sandesh Rao Mattu, A. Chockalingam
In this letter, we propose a learning based channel estimation scheme for orthogonal frequency division multiplexing (OFDM) systems in the presence of phase noise in doubly-selecti…

Deep Channel Prediction: A DNN Framework for Receiver Design in Time-Varying Fading Channels
Sandesh Rao Mattu, Lakshmi Narasimhan T, A. Chockalingam
In time-varying fading channels, channel coefficients are estimated using pilot symbols that are transmitted every coherence interval. For channels with high Doppler spread, the ra…
