Abstract

In this paper the combination of Transmit Antenna Selection with Linear Dispersion Code Selection is proposed and analysed. The bit error rate metric criterion is proposed (bit error rate minimization and throughput maximization) to evaluate the performances. The performance of the proposed spatial link adaptation scheme is evaluated under low mobility environment and MIMO uncorrelated Rayleigh channel. Concluded analysis shown that maximum spatial diversity is achieved as well as a smooth transition between codes with low spatial multiplexing rate and high spatial diversity (suitable for low SNR), and codes with high multiplexing rate but low diversity order (suitable for high SNR) in order to maximize the overall system throughput.
