Abstract :
We analyze the performance of multirate structures, implemented with a multiple codes (MC) scheme, and associated to multiuser detection (MUD) of successive interference cancellation (SIC) for a group of users (GSIC), considering a hyperbolic tangent (tanh) decision device in the intermediate stages. Extensive Monte Carlo simulations (MCS) were accomplished for the MC-GSIC tanh structure´s performance characterization, considering total and partial cancellation (with cancellation factor ξ<1) in additive white Gaussian noise (AWGN) and flat Rayleigh channels.
