Semi-Blind Channel Estimation and Pilot Allocation for Doubly-Selective Massive MIMO-OFDM Systems

This article addresses the problem of channel estimation and pilot allocation in massive multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) networks for sparse doubly selective (DS) channels. In DS channels, due to significant Doppler shifts, channels vary fast, a...
