Novel serial group interference canceller scheme for asynchronous multirate DS-CDMA systems
Paul Jean E. Jeszensky, Taufik Abrão · 2003
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 /spl xi/ < 1) in additive white Gaussian noise (AWGN) and flat Rayleigh channels.
