Dynamic transmit antenna shuffling scheme for mimo wireless communication systems

Abstract

In this paper, two novel dynamic transmit antenna shuffling schemes, namely 'Optimal' and 'Max STBC', are presented in order to reduce the interference in V-BLAST/STBC scheme. These antenna shuffling schemes with the channel state information (CSI) from the receiver, which significantly improves performance of the MIMO system in Rayleigh flat-fading channels by selecting the appropriate antenna shuffling pattern, have been compared with a few other related schemes in terms of BER and system capacity. The 'Optimal' antenna shuffling scheme improves the BER performance significantly with a gain of 2 dB at BER of 10 -3 compared to all other schemes, while the 'Max STBC' antenna shuffling scheme enhances the V-BLAST/STBC system capacity by 4 %. © 2012 Springer Science+Business Media.
