Beamformer-based Acquisition in MIMO-CDMA Communication Systems
2008
This paper proposes the code acquisition scheme on a MIMO channel for preamble search in a MIMO-CDMA uplink system. The performance of a ML code acquisition technique based on transmit and receive beamforming is analyzed by considering the detection probability. The acquisition performance and MAT for a MIMO code acquisition system are numerically evaluated. It is shown that the multiple transmit antennas can give the code acquisition system a transmit beamforming gain and result in much better performance than the corresponding scheme with a SIMO case.
