HARDWARE IMPLEMENTATION OF SMART ANTENNA SYSTEMS FOR HIGH SPEED WIRELESS COMMUNICATION

This paper presents some hardware implementation results of DOA (Direction Of Arrival) estimator and beamformer developed by our smart antenna project for high speed wireless data transmission. The present system employs smart antenna, FPGA-based digital signal processor and several analog & digital techniques in RF, IF and digital processing, and can estimate DOAs and do beamforming at very high speed and high accuracy. Performance of the present system is evaluated through some experiments.
