Wideband Channel Estimation for Full Rate Full Diversity Antenna Selection Wireless Systems

Journal of Applied Sciences, 2012, 12(13), 1378-1383.


In this study, we proposed a wideband channel estimator for full rate full diversity antenna selection wireless system with more than two transmit antennas in conjunction with the Orthogonal Frequency Division Multiplexing (OFDM) technology. This approach is based on the pilot-symbol-aided channel estimation where pilot symbols are inserted periodically through the OFDM frame at the transmitter. At the receiver, estimation of the channel at pilot locations are obtained, then, interpolating filter is used to get the estimated values of the channel at every location of the OFDM frame. Simulation results for different types of wideband channels with different Doppler frequencies are demonstrated.
