Abstract:
The third generation promises increased bandwidth up to 384 Kbits/s for wide area coverage up to 2Mbits/s for local area coverage. A smart antenna technique has been developed specifically to meet the bandwidth needs of 3G [5, 7, 12, 14]. Smart beamforming provides increased data throughput for mobile high speed data application. Here in this paper we worked on MVDR Beamforming scheme for continuing demand for increased bandwidth & better quality of services. Adaptive minimum variance beamforming can be easily implemented to increase capacity as well as suppressing co-channel interference & to enhance the immunity to fading. The computer simulation carried out in MATLAB platform shows the signal processing technique optimally combines the components in such a way that it maximizes array gain in the desired direction simultaneously minimize it in the direction of interference [1, 3, 15, 16].
