Decision-Feedback Multiuser Detection in Multicell Multicarrier DS-CDMA Systems with/without BS Cooperation

Decision-Feedback Multiuser Detection in Multicell Multicarrier DS-CDMA Systems with/without BS Cooperation
Decision-Feedback Multiuser Detection in Multicell Multicarrier DS-CDMA Systems with/without BS Cooperation
Abstract—In this contribution, we investigate the signal detection in the multicarrier direct-sequence code-division multiple-access (DS-CDMA) systems employing both time (T)-domain and frequency (F)-domain spreading, which are referred to as the TF/MC DS-CDMA systems. A multicell scenario with universal frequency reuse is considered, where signals experience frequency-selective Rayleigh fading. A decision-feedback multiuser detector (MUD), which represents the extension of a so-called receiver multiuser diversity aided multi-stage minimum mean-square error MUD (RMD/MS-MMSE MUD), is employed to cope with both the intracell multiuser interference (MUI) and intercell interference (ICI), when base-station (BS) cooperation is or is not assumed. Furthermore, when BS cooperation is assumed, symbols detected at different BSs are interchanged
and combined to enhance the detection performance. Our studies and performance results demonstrate that the RMD/MS-MMSE MUD constitutes one of the promising multicell processing (MCP) schemes, making it possible for each cell to support heavily overloaded users, even when a frequency-reuse factor one is applied.
