Performance of Smart Antennas with FPGA Signal Processors over 3G Antennas

B. Bhuvaneswari, B. Karthikeyan

Abstract


Demands for increased capacity and better quality of service are driving the development of new wireless technologies such as “smart” antenna arrays. The FPGAs operate as powerful digital signal processing devices, which can meet the requirements of adaptive antenna arrays. The smart antenna systems are efficient than the existing 3G antenna systems as they can track the location of a mobile user and also increase channel capacity through spatial diversity. FPGAs offer greater flexibility for performing functions such as acquisition control, digital down-conversion, demodulation and matched filtering. This paper discuses in creating beam-forming smart antennas using FPGA’s as well as the ways in which smart antennas will overcome the performance of 3G antennas.
