Density evolution for multistage CDMA multiuser detector

Toshiyuki Tanaka

    Research output: Chapter in Book/Published conference outputChapter


    An analytical framework to analyze the stage-by-stage detection dynamics of the multistage CDMA multiuser detector is presented. The density evolution idea is applied to analyze the multistage detector. Message distribution is treated basically by a Gaussian approximation, but interstage correlation of messages is systematically taken into account, which turns out to provide significant improvement.
