Satellite communication system design

We design softwares to detect satellite communication signals.

Virtual Full-Duplex Relaying in Cellular Systems

We are building a relay system that will achieve the performance of full-duplex relaying using half-duplex relays. This system is based on a novel relaying protocol proposed by us recently. We plan to build a virtual full-duplex testbed using commercial off-the-shelf software defined radios. Please see my publications for the details of this protocol.

• Designed at - IIT Kanpur.

• [Status] - Ongoing.

4G Radio Access Network Testbed

A testbed consisting of four base stations and twelve users was built at IIT Madras to experimentally investigate the novel wireless communication algorithms in realistic fading and interference settings. As a part of this project, I designed, built and tested the testbed hardware from scratch, and also developed LTE PHY layer algorithms to exercise the testbed.

• Designed at - Center of Excellence in Wireless Technology (CEWiT).

• [Status] - Complete.

Design of WiMAX Base Station and User Equipment.

The objective was to build a WiMAX system using an off-the-shelf WCDMA radio. For this project, I built a common hardware platform for both base station and user equipment and also developed WiMAX physical layer algorithms.

• Designed at - Midas Communications.

• [Status] - Complete.
