Abstract:

In vertical-Bell laboratory layered space-time (V-BLAST) systems, the detection of received signal needs rich scattering channel environment, otherwise the system bit error rate (BER) performance descends seriously. A transmit antenna selection algorithm based on V-BLAST orthogonal frequency division multiplexing (OFDM) systems is proposed to solve this problem in this paper. This algorithm selects the transmit antenna subset that will maximize the minimum signal-to-noise-plus-interference ratio (SNIR) on each sub-carrier. Theoretical analysis and computer simulation results show that the system BER performance is significantly improved by this algorithm.

Key words: vertical-Bell laboratory layered space-time, orthogonal frequency division multiplexing, multiple-input multiple-output, antenna selection
