Raj Bhattacharjea

Picture of Raj Bhattacharjea I am an Electrical Engineer working as the Director of Machine Learning for DeepSig Inc. I'm also an Adjunct Principal Research Engineer with the School of Electrical and Computer Engineering at Georgia Tech. My goals include conducting, publishing, and productizing research in machine learning for communication and sensing systems. You'll find a bit about me here, and once in a blue moon I'll post other content about topics I'm interested in.

Research Interests

The common threads that tie together my work are:

Electromagnetics / Computational EM
Signal processing
Machine learning

At various times I've been interested in applying these techniques to the following domains:

Commercial wireless communications
Free space optical communications
Fiber optic communications
Photonic signal processing
Near-field inductive communications
Backscatter communications

Courses Taught (Georgia Tech)

ECE3025 Electromagnetics, Spring 2019

ECE2026 Intro to Digital Signal Processing, Summer 2018 and Fall 2018

ECE4012 Senior Capstone Design, Spring 2016

Pre-Prints, Papers, and Presentations

Last updated February 2025.

Pre-Print: 3D Geometry Extraction for Sionna RT and Sensitivity Analysis

Site-Specific Propagation Measurements Improve Learned 5G Processing Algorithms

An arXiv preprint is available for those without IEEE Xplore access

Pre-Print: Encoder-Decoder Networks for Signal Bandwidth Estimation on Arrays

This one was accepted for publication at IEEE Array 2022 and my co-author, Nathan West, presented results of this work at the conference. However, we missed the deadline for submitting the final camera-ready files for archival on IEEE Xplore (oops). So, here's the arXiv version.
