Low‐complexity transmit antenna selection algorithm exploiting null space in spatial multiplexing UWB MIMO systems

Abstract

In this paper, a new transmit antenna selection algorithm for spatial multiplexing ultra-wideband multiple-input multiple-output systems is proposed. It utilizes the null space of the channel matrix spatially and temporally combined for available transmit antennas. A selection strategy is used to successively find and remove the transmit antennas having the largest contribution to the null space. Its error performance is shown to be close to that of the optimal antenna selection algorithm with low complexity.

MIMO-Orthogonal space time block code system joint with BCH-TC in Rayleigh fading channel for performance of transmit antenna selection

“…The joint of STBC and TAS incorporated with TC obtained more than 4 dB SNR gain values (González et al , 2016). The common selection combining technique used for cognitive radio is proposed in Kim (2017).…”
