Combating Near Far Effects of linear MMSE Multiuser Detection in coded OFDM-CDMA

Authors: M. Feuersänger, V. Kühn
Abstract: This paper deals with near far effects encountered in MMSE linear multiuser detection and proposes a method to mitigate the transmit-power dependent user-specific bit error rates by introducing an additional postprocessing by a combination of nonlinear parallel and successive interference cancellation. Throughout the paper we consider a quasisynchronous (i.e. asynchronous with coarse synchronization at the receiver) OFDM-CDMA uplink transmission as well as perfectly known channel impulse responses.
