In this paper we address the problem of blind recovery of multiple OFDM streams in a multiple-input multiple-output (MIMO) system. We propose an equalization algorithm which is based on a combined criterion that cancels both inter-symbol interference (ISI), and co-channel interference (CCI). ISI is minimized by using a modified vector constant modulus (VCM) criterion, while CCI is minimized by a decorrelation criterion.
