In this paper, we proposed a random channel allocation scheme for SDMA system and compared it with first duplicate(FD) and duplicate later(DL) scheme. Theoretical analysis and simulation results show that the system performance parameter like capacity and business blocking probability of the scheme we proposed is of feasibility while saving the time for allocate the channel and can distributing business to each channel more evenly .
