A Rotation-Based Quasi-Orthogonal Space-Time Block Coded OFDM System over Frequency-Selective Channels

Abstract: In this paper, we apply Quasi-Orthogonal Space - Time Block Code through Constellation rotation (QOSTBC_CR) in OFDM system, construct the QOSTBC_CR-OFDM code and propose the decoder. Since ...
