Title
Blind multi-user detection for multi-carrier CDMA systems with uniform linear arrays
Abstract
To mitigate the inter-chip and inter-symbol interferences (ISI), multi-carrier code-division multiple access (MC-CDMA) communication systems, which integrate the advantages of multi-carrier transmission systems with those of CDMA, are considered as promising techniques for future broadband wireless multimedia communications. In this paper, we focus on the uplink multi-user detection (MUD) on the scheme that a uniform linear array (ULA) is applied to the base station of the MC-CDMA system. We first describe the equivalent spatial-temporal channel model of multi-user multiple-input multiple-output (MIMO) MC-CDMA systems. Based on this scheme, by utilizing the finite alphabet property of transmitted symbols, an multi-user detector is derived for the MC-CDMA system with the ULA over frequency-selective fading channels. Computer simulations illustrate that our algorithm is more robust against noise and can well mitigate multiple access interference (MAI) in multi-user scenarios. In particular, the proposed scheme has the potential of providing the anticipated MUD performance gains with a complexity that would be manageable for MC-CDMA systems.
