    Abstract

    Layered space time processing in spatial multiplexing systems has a stringent requirement that the number of receive antennas must be equal to or larger than the number of transmit antennas. A novel concept of virtual receive antennas (VRA) proposed in our previous work can loosen this requirement. In this paper, we present a low complexity frequency domain equalizer (FDE) and show the potentials of VRA by analysing the system capacity. In addition, we consider a more practical pulse shaping Alter for the VRA system. Results show that the VRA system can achieve higher ergodic capacity and outage rate than the conventional overloaded MIMO system. With the proposed low complexity FDE receiver, VRA allows layered processing for spatial multiplexing system with less number of physical antenna. © 2008 IEEE.
