Abstract
This paper applies a MIMO transmit preprocessing method proposed by Choi, 2004 into OFDMA systems. Multiuser scheduling in joint frequency and spatial domain is studied. A suboptimal two step scheduling (TSS) algorithm for the system throughput maximization is proposed with reduced complexity. The performance is showed by computer simulation with the value of spatial domain scheduling
