We present a method of tractable complexity for joint data detection and channel estimation DS/CDMA signals. The scheme results from an application the SAGE algorithm. Monte Carlo simulations synchronous scenario show that is near-far resistant it robust against errors parameters. Moreover, very short training sequences are required to converge. Simulation further demonstrate better performance obtained when users' bit cyclically updated in order increasing strength signals at output whitening filter receiver.
