On improved DCT based Channel Estimation with very low complexity for MIMO-OFDM systems

A Novel Data-Aided Channel Estimation with Reduced Complexity for TDS-OFDM Systems

Abstract—Diagonal Bell Laboratories Layered Space-Time (DBLAST) structure offers a low complexity solution to realize the attractive capacity of Multiple-input and multiple-output (MIMO) systems. In this paper, we apply D-BLAST in orthogonal fr
