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.
