This paper considers a multiuser spectrum sharing (SS) multiple-input multiple-output (MIMO) system with zero-forcing (ZF) operating in a Rayleigh fading environment. We provide an asymptotic sum-rate analysis to investigate the effects of different parameters on the multiuser diversity gain. For a ZF SS spatial multiplexing system with scheduling, the asymptotic sum-rate scales like N t log 2 (Q( Nt Np √K - 1)/N t ), where N p denotes the number of antennas of primary receiver, Q is the interference temperature, and K represents the number of secondary transmitters.
