✦ Synopsis
Multistage interference cancelers are deemed to be one of the most realizable schemes for asynchronous DS-CDMA. While limited to SD (Soft Decision)-based parallel multistage cancellation, this paper covers (1) theoretical relations introduced between suppressing factors and interference canceling gains, and (2) computer simulation results confirming the validity of the theory. There are two ways of setting suppressing factors. One is to set common values for all stages, and another is to set an individual value for each stage. This paper also discusses the differences between the two types of setting suppressing factors.
