Multi-user orthogonal frequency division multiplexing (OFDM) with antenna arrays has been extensively investigated in the past with success. However, the performance of this type of OFDM in realistic multipath fading environments is limited when the number of carriers is small (i.e. less than 128 carriers are employed). In addition, the space correlation between different antenna elements was neglected in the past studies of this system. In this paper, a technique based on over-sampling at the… CONTINUE READING
