This letter presents a new algorithm for automatic modulation classification (AMC) and its implementation and validation as an intellectual property (IP) core. AMC aims at accurately identifying the modulation scheme of a given communication system in a short period of time. The proposed IP core consists of a multiclass classifier composed by linear support(More)
The automatic modulation classification (AMC) problem aims at identifying the modulation scheme of a given communication system with a high probability of success and in a short period of time. AMC has been used for decades in military applications in which friendly signals should be securely transmitted and received, whereas hostile signals must be(More)
In this paper we investigate the use of the Support Vector Machine (SVM) approach to develop simple and efficient VLSI architectures for real-time digital modulation classification. Such simplicity and efficiency arise from the adoption of a front end block that is based on histograms. Particularly, we compare two decision schemes to solve the multiclass(More)
