Software Defined Radio and Anti-jamming

The signal design calls for mitigation of the multipath fading and interference in the new generation of system. The receiver design also should be modernized to tackle weak signal acquisition and tracking. In this work, we study the Multiplexed Binary Offset Carrier modulated signal receiver exhaustively and also explore the applicability of new emerging techniques for tracking and anti-jamming. Here we will develop two goals. 1) Tracking unit of heterodyne receiver and 2) jamming and anti-jamming algorithm using state of art adaptive filters. At last, we will evaluate the models in terms of bit error rate and receiver operating characteristics.

About the Project

In this era, we almost forgot the compass because of Global Positioning System (GPS) for finding any location on Earth. Now-a-days as modernization of radio-navigational satellite systems persist, there is an increasing interest in new generation signals and systems for civilian use. The present-day telecommunication has witnessed the introduction and rapid progress of existing major global radio navigational satellite systems like GPS (Global Positioning System), GALILEO, GLONASS (Globalnaya Navigatsionnaya Sputnikovaya Sistema or Global Navigation Satellite System) and Compass. The Regional Navigational Satellite Systems (RNSS) like Beidou, Quasi-Zenith Satellite System (QZSS) and Indian Regional Navigational Satellite System (IRNSS) are also being simultaneously developed. The congested allocated frequency bands of satellites of different navigational satellite system poses technical and receiver performance in presence of heavy interference.
