Abstract

In this paper, we compare and evaluate several opportunistic round robin (ORR) scheduling for V-BLAST users over uplink MIMO channels. Each user spatially multiplexes his data over multiple transmit antennas. This spatial multiplexing scheme provides high data rates while multi-user diversity obtained from scheduling improves the performance of the uplink system. The opportunistic round robin scheduler is totally fair and it allows all users to access the channel. In the same time it captures part of the available multiuser diversity. The main results of this study show the performance gains of using ORR compared to RR scheduling. In addition, we compare the performance to the greedy and proportional fair algorithms in term of BER and supported capacity at different number of users.
