MIMO-OFDM for wireless communications: signal detection with enhanced channel estimation

  title={MIMO-OFDM for wireless communications: signal detection with enhanced channel estimation},
  author={Geoffrey Ye Li and Jack H. Winters and Nelson Sollenberger},
  journal={IEEE Trans. Communications},
Multiple transmit and receive antennas can be used to form multiple-input multiple-output(MIMO) channels to increase the capacity by a factor of the minimum number of transmit and receive antennas. In this paper, orthogonal frequency division multiplexing (OFDM) for MIMO channels (MIMO-OFDM) is considered for wideband transmission to mitigate intersymbol interference and enhance system capacity. The MIMO-OFDM system uses two independent space-time codes for two sets of two transmit antennas. At… CONTINUE READING
