Joint Transmit Beamforming and Antenna Selection in MIMO Systems.
IEEE Wireless Communications Letters(2018)
摘要
This letter investigates joint beamforming and antenna selection (JBAS) for a spatial diversity multiple-input multiple-output system, where the transmitter equipped with multiple antennas performs both antenna selection and beamforming optimization to maximize the received signal-to-noise ratio (SNR). The JBAS problem is NP-hard to solve due to a sparsity constraint. In this letter, we propose sm...
