OpenGERT: Open Source Automated Geometry Extraction with Geometric and Electromagnetic Sensitivity Analyses for Ray-Tracing Propagation Models
Serhat Tadik, Rajib Bhattacharjea, Johnathan Corgan +3
Accurate RF propagation modeling in urban environments is critical for developing digital spectrum twins and optimizing wireless communication systems. We introduce OpenGERT, an op…
How Critical is Site-Specific RAN Optimization? 5G Open-RAN Uplink Air Interface Performance Test and Optimization from Macro-Cell CIR Data
Johnathan Corgan, Nitin Nair, Rajib Bhattacharjea +4
In this paper, we consider the importance of channel measurement data from specific sites and its impact on air interface optimization and test. Currently, a range of statistical c…
Encoder-Decoder Networks for Self-Supervised Pretraining and Downstream Signal Bandwidth Regression on Digital Antenna Arrays
Rajib Bhattacharjea, Nathan West
This work presents the first applications of self-supervised learning applied to data from digital antenna arrays. Encoder-decoder networks are pretrained on digital array data to…
High-Capacity Complex Convolutional Neural Networks For I/Q Modulation Classification
Jakob Krzyston, Rajib Bhattacharjea, Andrew Stark
I/Q modulation classification is a unique pattern recognition problem as the data for each class varies in quality, quantified by signal to noise ratio (SNR), and has structure in…
Modulation Pattern Detection Using Complex Convolutions in Deep Learning
Jakob Krzyston, Rajib Bhattacharjea, Andrew Stark
Transceivers used for telecommunications transmit and receive specific modulation patterns that are represented as sequences of complex numbers. Classifying modulation patterns is…
