The performance of the system with maximal ratio combining and multiuser scheduling is studied in the multiuser uplink in the presence of unequal power cochannel interferences from other cells.The channels of useful and interference signals are assumed to be Nakagami-
m
and Rayleigh fading.The closed form expressions for outage probability and average symbol error ratio (ASER) of system are derived by using performance analysis method based on probability density function.Simulation results show that
the analytical curves of the derived expressions match well with the numerical simulations
and the increase of the number of receive antennas and users are both of benefit to the improvement of system performance due to multi-antenna and multiuser diversity
and the presence of a predominant interferer deteriorates the outage per
