Abstract
This paper deals with the design and analysis of low complexity user scheduling algorithm in multiantenna broadcast (downlink) systems under zero-forcing multiplexing. By using quantization technology, the channel matrix can be divided into serval unoverlapped channel regions. Based on the quantized channel regions, we can get semi-orthogonal region sets. The presented user scheduling algorithm in this paper is based on using the semi-orthogonal region sets. Simulation results shows that this algorithm can achieve a sum rate close to the full searching algorithms while with much lower complexity than those of the previous algorithms.
