Abstract: Timing offset and channel estimation plays an important role in the performance of amplify-and-forward two-way relay networks. The state-of-the art approach models the system as a Hidden ...
Abstract: Joint activity detection and channel estimation is a crucial task in grant-free random access for massive machine-type communications. To enhance communication quality, intelligent ...
Every day, thousands of images and signals are collected at sea. Sonar, buoys, satellites, and cameras installed on ships generate enormous amounts of data. Artificial intelligence (AI) is already ...
Overview This repository provides a reusable Gaussian Mixture Model implementation trained with Expectation-Maximization using pure numpy. It supports full, diagonal, and spherical covariances, ...
