Abstract:
In simple words, smart antenna is such that it can sense its environment and can adjust
its gain in different directions accordingly. They provide a smart solution to the problem
of communication traffic overload i.e. they increase the traffic capacity. They also
improve the QOS.
RF spectrum is a limited resource and is becoming crowded day by day due to the
advent of new technologies. The sources of interference are increasing as well and hence
interference is becoming the limiting factor for wireless communication.
Smart Antenna adapts its radiation pattern in such a way that it steers its main
beam in the DOA (direction of arrival) of the desired user signal and places null along
the interference. It refers to a system of antenna arrays with smart signal processing
algorithms.
This project aims to implement a complete smart antenna system with an
altogether different hybrid biological technique which gives better results than the
previous algorithms used in this regard. We have done both pats here i.e. DOA
Estimation and Beamforming. We have developed its code using MATLAB. We have also
implemented it on DSP-Kit. Instead of using actual signals, we have used dummy signals,
which are fed to DSK- C6713 for processing.
