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.
