Automatic modulation classification using techniques from image classification
نویسندگان
چکیده
Automatic Modulation Classification (AMC) is a rapidly evolving technology, which can be employed in software defined radio structures, especially 5G and 6G technology. Machine Learning (ML) provide novel efficient technology for modulation classification, systems working low signal to noise ratio (SNR). In this article, two dynamic not reliant on received phase lock frequency are presented, with both employing ML classify the types different SNR. The first model developed from previous existing literatures, utilises constellation images (CI) image classification Here, detected way without lock. second model, new method named Graphic Representation of Features (GRF) proposed, represents statistical features as spider graph ML. concepts tested verified using simulations RF data lab (SDR). results models compared. With GRF techniques an overall accuracy 59% observed 0 dB SNR 86% at 10 SNR, compared random guess 25%.

One component of wireless communications of increasing necessity in both civilian and military applications is the process of automatic modulation classification. Modulation of a detected signal of unknown origin requiring interpretation must first be determined before the signal can be demodulated. This thesis presents a novel architecture for a modulation classifier that determines the most l...
متن کاملNovel Automatic Modulation Classification using Correntropy Coefficient
This paper deals with automatic modulation classification (AMC) of communication signals. A new method for the automatic classification using a similarity measure derived from Information Theoretic Learning (ITL), called correntropy coefficient, is proposed. Unlike many of the conventional methods, the proposed method does not require any signal pre-processing. Further, the proposed AMC techniq...
