In this paper, two fractionally-spaced space frequency equalization schemes for the downlink of broadband single-carrier multi-user MIMO-CDMA system are proposed. In the first scheme, the fractionally-spaced space frequency equalizer is used to combat the Inter-Code Interference (ICI) and Co-Channel Interference (CCI) induced by MIMO frequency selective fading channels. Under the condition that the spreading codes of all active users are known at the receiver, the second scheme combines fractionally-spaced space frequency equalizer with Parallel Interference Cancellation (PIC), which can reduce the Inter-Antenna Interference (IAI) further. Compared with the conventional frequency domain equalization schemes, the proposed fractionally-spaced space frequency equalization ones have better performance with low complexity.
