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

چکیده
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.

متن کاملCoupling Effects and Performance of Loran Transmitter Antennas
It is known that if a conductor resides in the neighboring of an antenna with a small distance relative to the wavelength, it induces a reverse current on the conductor. This paper involves the unavoidable coupling effects on some common types of LF antennas, due to the large wavelength in this frequency band. In particular, after some discussions about top-loaded antennas, the coupling effect ...
متن کاملApplication of Smart Antennas to Wideband Code Division Multiple Access : the Uplink Performance
Adaptive antenna arrays have recently been introduced to cope with the high capacity required by the 3 generation (3G) wireless communications systems. As adaptive antenna arrays focus narrow high gain beams towards the desired user and nulls towards interferers, both coverage and capacity of the network can be improved. To establish the performance gain that a smart antenna can deliver in a 3G...
