Centre for Advanced Communications Lab

Advanced Communication laboratory was setup as an initiation taken up by Department of Electronics and Communication, BVRITN in 2016. It is envisioned as an umbrella body, under the aegis of which all communication related activities of the Department will be coordinated. The main emphasis of the laboratory is to design and develop RF/antenna modules, radar signal processing, modulation schemes, parametric characterisation of wireless modules, software defined radio applications, different wireless standards and work on research problems and innovative projects that extend the state of the art of wireless systems. The vision behind is to promote and encourage student activities, research projects and relevant courses related to this field.

Radar Signal processing Setup

Radar Signal processing setup deals with a High Resolution Radar (HRR) target detection system which is basically a pulse compression radar. HRR detection system is used for processing poly alphabetic signal at larger pulse compression ratio using phase coded pulse compression sequences. Using this system it is proposed to set up coincidence detection scheme to achieve effective point/distributed target detection.
