摘要： A wireless multiple-input multiple output (MIMO) communication system includes signaling simulcasting. Base stations include a plurality of transmit antennas and terminals include a plurality of receive antennas to form MIMO channels. In one embodiment, a simulcasting MIMO wireless communication system includes orthogonal frequency division multiplexing (OFDM). This arrangement achieves the spectral efficiency advantages of OFDM and simulcasting.

摘要： A MIMO OFDM system includes a plurality of space-time encoders for encoding respective data blocks with independent space-time codes. The transformed data block signals are transmitted by a plurality of transmit antennas and received by a plurality of receive antennas. The received data is pre-whitened prior to maximum likelihood detection. In one embodiment, successive interference cancellation can be sued to improve system performance. Channel parameter estimation can be enhanced by weighting the channel impulse response estimates based upon a deviation from average.
