Smart antenna system implementation based on digital beam-forming and software radio technologies

This paper presents the design and implementation of a complete receiving smart antenna system. By using software radio techniques, the system can be re-programmed to meet different modulation standards. The platform consists of antenna array, RF module, digital IF module and digital signal processing module. Digital beam-forming and demodulation algorithms are all Implemented on DSP. Experimental results are shown for both anechoic chamber and outdoor measurements.
