Modulation classification (MC) is the first step performed at the receiver side unless the modulation type is explicitly indicated by the transmitter. Machine learning techniques have been widely used for MC recently. In this paper, we propose a novel MC technique dubbed as Joint Equalization and Modulation Classification based on Constellation Network (EMC2-Net). Unlike prior works that considered the constellation points as an image, the proposed EMC2-Net directly uses a set of 2D constellation points to perform MC. In order to obtain clear and concrete constellation despite multipath fading channels, the proposed EMC2-Net consists of equalizer and classifier having separate and explainable roles via novel three-phase training and noise-curriculum pretraining. Numerical results with linear modulation types under different channel models show that the proposed EMC2-Net achieves the performance of state-of-the-art MC techniques with significantly less complexity.

Constellation is a distributed network that enables fast, scalable solutions for organizations who need to process and transfer data securely and build interoperability for connected sensors and devices. As computing moves increasingly to the edge, Constellation provides the only scalable, secure solution for a world with more connectivity, more centralization, and more concentrated risk. Rather, the initiative aims to create a universally compatible "knowledge application." As a result, Constellation employs a "hybrid of cryptocurrency/blockchain, distributed systems computing, machine learning, and enterprise (SME) adoption" that combines numerous methodologies. The Constellation Hypergraph network uses directed acyclic graph (DAG) technology to introduce a revolutionary "L 0 state channel" and token standard.

Constellation Network is a decentralized, open-source, and permissionless programming platform that allows anybody to create apps. Constellation also provides complete control over the tokenomic structure and incentives of apps. Constellation Network, on the other hand, is much more than a decentralized playground and toolbox.
