Transmit Antenna Selection and Receive User Scheduling for the Downlink of Multi-User MISO Systems

We consider the downlink of multiuser multiple input single-output (MISO) wireless systems, where the base station is equipped with multiple antennas and each mobile user is constrained to one single antenna. In particular, we consider linear precoding systems such that the single antenna receivers do not have to estimate the channel, but only scale and quantize the received data. In this scenario, we propose a low complexity transmit antenna selection and user scheduling algorithm. The low complexity transmit antenna selection and user scheduling algorithms shown that the proposed algorithm obtains near optimal performance.
