Channel Estimation and Equalization for Alamouti SF-Coded OFDM-UWA Communications
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021-02)In this paper, a new channel estimation and equalization algorithm for underwater acoustic (UWA) communications is presented. The proposed algorithm is developed to meet the requirements of underwater time-varying sparse ... -
Subspace-Based Estimation of Rapidly Varying Mobile Channels for OFDM Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021)It is well-known that time-varying channels can provide time diversity and improve error rate performance compared to time-invariant fading channels. However, exploiting time diversity requires very accurate channel estimates ...
