Variable antenna-space shift keying for high spectral efficiency in exponentially correlated channels

Abstract

the case of correlated channels. Then, to reduce the correlation effect, a novel antenna codeword construction method that minimizes the pairwise error probability is introduced for exponentially correlated channels. Codeword sets are obtained for k = 3 and 8 bits/s/Hz for 7 and 13 transmit antennas. Simulation results show that variable antenna-SSK gets better performance according to its counterparts with increasing effect of correlation.
