Sparse Channel Estimation for MIMO Index Modulated OFDM Based Underwater Acoustic Communications
Abstract
This paper presents a novel channel estimation algorithm for pilot aided MIMO-OFDM-IM underwater acoustic communications. The receiver employs the least squares technique for the initial channel coefficients estimation. Then, using the ESPRIT algorithm, t
