Abstract :
The performance of multirate structures, implemented with the multiple codes (MC) scheme, and associated with multiuser detection (MuD) of successive interference cancellation (SIC) for group of users (GSIC), considering a hyperbolic tangent (named hereafter as tanh) decision device in the intermediate stages, is analyzed. 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.
