| Abstract: | A new -steering method to suppress Doppler-shifted signals is proposed for orthogonal frequency-division multiplexing adaptive array antenna. The proposed array antenna has a simple structure and can steer s for interfering signals even with small Doppler shifts by forcing virtual subcarrier outputs to be zero. A multistep recursive least-square algorithm is proposed to control the array weights and the bit-error rate and antenna pattern are evaluated by computer simulation. |
