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,...
In downlink broadcast channels, the multiple-antenna base station (BS) often communicates with several users simultaneously. However, the co-channel interference increases as the number of users increases, therefore, BS can not afford too many users. So user selection is necessary. In this paper, we propose a suboptimal user selection algorithm based on signal-to-leakage-noise ratio (SLNR) for the...
