IEEE Communications Society - Atlanta Chapter


Dr. Rajib Bhattacharjea is a research engineer in the Georgia Tech Research Institute Information and Communications Laboratory. He will be presenting his work on SDRs. Below is the abstract for this presentation. Lunch will be served at 11:30 a.m.

Abstract:

The combination of low-cost, low-power, embedded computers with software defined radio has the potential to disrupt communications markets and paradigms. The embedded computers in question are known as single board computers (SBCs), and have become increasingly available, capable, and low-cost. They are the platform of choice for projects that require modest computing capabilities in the do-it yourself, maker, and hacker communities. The past ten years have also seen an unprecedented rise in commercial off-the-shelf software-defined radio (SDR) technology. At the time of writing, a non-exhaustive, crowd-sourced list of commercially available SDRs lists 84 different commercially available models, ranging in price from $8 to $6000. These have RF transmitting and/or receiving capabilities, and interface with a generic computer that performs the signal processing. Open source tools for doing the signal processing using SBCs are readily available. This combination of SBC, SDR, and open source software is a powerful tool for implementation of almost arbitrary radio and wireless communications technologies.

This talk will cover a selection of topics in commercial embedded computers and commercial SDR technology. A list of available, Linux-compatible, commercial SDR-compatible, embedded computers will be presented. Commercial SDR products will also be presented, and some combinations of these technologies will be discussed and demonstrated, chiefly focusing on the low-cost alternatives. Some common pitfalls in Linux and open source radio signal processing on embedded platforms will be addressed. The general capabilities of various platforms at different price points will be discussed in terms the tradeoffs involved.

Dr. Rajib

Topic:

Commercial Software Defined Radios

Research Engineer at GTRI.

Biography:

Dr. Rajib Bhattacharjea received his BS, MSECE, and Ph.D. degrees from Georgia Tech. He specializes in the modeling and simulation of long-range radiofrequency links for wireless telecommunications, radar, and electronic warfare applications. While pursuing his Ph.D., he was a member of the research faculty and a research consultant for the US Naval Academy, where he developed a novel computational model for radiofrequency propagation prediction near the surface of the earth in the presence of atmospheric refractive effects. He currently is a research engineer in the Georgia Tech Research Institute Information and Communications Laboratory, where he works on propagation modeling and software defined radio for electronic warfare scenarios. His other research interests include wideband wireless channel measurements and backscatter communications. He is an active reviewer for several IEEE journals and magazines.





Agenda

Before the event:

Please RSVP by Saturday, April 7th, 2018 to syed.tamseel@ieee.org if you plan to attend so we have an accurate count for lunch. Parking is free.

On the day of event:

The GTRI Conference Center is on the left as you drive in.

Free visitor parking is available in designated areas on the second level of the parking deck next to the building. Drive in between the two buildings towards the gate arm. The gate arm will open automatically upon approach, and then one can proceed up the ramp to the second level.

Further instructions under the instance for non-availability of designated visitor parking spots will be sent out shortly.

Lunch will be served at 11:30 a.m. and Dr. Rajib's presentation will begin at 12:00 p.m.
