| Content Summary | The recent concept of large-scale multiple-input multiple-output (MIMO) systems has attracted substantial research attention and been regarded as a promising technique for next-generation wireless communications networks. Combined with the cost of analog radio-frequency chains it necessitates to work on the use of efficient antenna selection (AS) schemes. Signal-to-noise ratio (SNR) optimal transmit antenna selection and beamforming for a MIMO system that consists of a large number of transmit antennas has been considered in this work. We examine an algorithm that has polynomial complexity and solves the transmit AS problem for maximum-SNR joint beamforming with two receive antennas and under a total power constraint. Furthermore, this thesis works on the beamforming vector approximation under a per-antenna-element power constraint on the transmitter, a problem which has not been efficiently solved so far and many suboptimal algorithms have been produced to tackle this problem. Some of them are examined and compared in this thesis. | en |
