In this paper, we apply particle filtering to multiuser detection (MUD)in synchronous CDMA systems with perfect channel state information (CSI). To apply particle filtering to MUD, first we find a factored representation of the posterior distribution. We show that the whitened matched filter (WMF) output allows such representation. No system approximations are made and the method is ``soft'' in nature. As a result, a near optimum performance is observed in simulations both in the equal power case and the near-far case. Since the computational complexity of the method is not exponential with the number of users, the method may have potential for industrial application.
