Abstract :
This paper addresses the employment of an antenna subset selection algorithm for differential space-time block codes (DSTBC). The antenna subset selection is based on maximizing the Frobenius norm of the channel matrix. The performance of the algorithm over Rayleigh and Rician slow fading channel is investigated comprehensively. The performance of the algorithm is compared with the optimal algorithm and the reason of the difference is investigated. In addition, the effect of K-factor of Rician channel on the performance of antenna subset selection is studied. The simulation results show a significant improvement in using antenna selection for DSTBCs as a means of decreasing bit-error-rate (BER) by increasing diversity gain.
