Multi-Carrier Code Division Multiple Access (MC-CDMA) is an attractive multiple access technique. For achieving a very high speed data transmission with a limited bandwidth, MCCDMA can be jointly used with Multiple-Input Multiple-Output (MIMO) multiplexing. Among many signal detection methods, an iterative interference cancellation technique can be used. The presence of residual interference limits the performance improvement. In this paper, the authors consider the Minimum Mean Squared Error Detection (MMSED) with imperfect cancellation of Inter-Code interference (ICI) and Inter-Antenna Interference (IAI) and derive the capacity expression by taking into account the degrees of residual ICI and IAI.
