Polar Coding and Random Spreading for Unsourced Multiple Access
Asit Kumar Pradhan, Vamsi K. Amalladinne, Krishna R. Narayanan +1
This article presents a novel transmission scheme for the unsourced, uncoordinated Gaussian multiple access problem. The proposed scheme leverages notions from single-user coding,…
An enhanced decoding algorithm for coded compressed sensing
Vamsi K. Amalladinne, Jean-Francois Chamberland, Krishna R. Narayanan
Coded compressed sensing is an algorithmic framework tailored to sparse recovery in very large dimensional spaces. This framework is originally envisioned for the unsourced multipl…
Spatially-Coupled Neural Network Architectures
Arman Hasanzadeh, Nagaraj T. Janakiraman, Vamsi K. Amalladinne +1
In this work, we leverage advances in sparse coding techniques to reduce the number of trainable parameters in a fully connected neural network. While most of the works in literatu…
Sparse IDMA: A Joint Graph-Based Coding Scheme for Unsourced Random Access
Asit Pradhan, Vamsi Amalladinne, Avinash Vem +2
This article introduces a novel communication paradigm for the unsourced, uncoordinated Gaussian multiple access problem. The major components of the envisioned framework are as fo…
