Abstract :
This paper shows performance of a transmit beamforming with DOA estimation in fast time selective fading channels with angle of arrival spread. The performance is confirmed by simulation where carrier frequency is assumed to be 20GHz and a linear array antenna is introduced. The unitary ESPRIT is applied for the DOA estimation. The beamfoming gain can be kept high as far as the maximum Doppler frequency fD is less than 104 in the fading channel.
