摘要：
This paper addresses the problem of blind multi-user equalization for OFDM. A Vector Constant Modulus Algorithm (VCMA) is developed for a specific Multiple Input-Multiple Output (MIMO) system. The proposed algorithm relies on a combined criterion, to cancel both inter-symbol-interference (ISI) and inter-user-interference (IUI). ISI is minimized by using a constant mean block energy criterion, while IUI is reduced by using a decorrelation criterion. Reliable performance is achieved with relatively fast convergence and small steady-state error, as well as low computational complexity.
