Power distribution grids (PDGs) are one of the main parts of electrical logistic chains with the
task of transferring electricity to the consumers continually. Adverse weather conditions …

It is an important work to classify the modulation type of the intercepted radar signal for an
electronic intelligence (ELINT) receiver in a non-cooperative environment. The authors use …

Intra-pulse modulation recognition under negative signal-to-noise ratio (SNR) environment
is a research challenge. This article presents a robust algorithm for the recognition of 5 types …

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 …

In many practical application scenarios, radio communication signals are commonly
represented as a spectrogram, which represents the signal strength measured at multiple …

In some radio communication scenarios it is useful to extract the bandwidth and start/end
times of each transmission in a spectrogram. However, few methods in the literature are able …

Signals in a non cooperative communication environment such as in the high frequency
(HF) spectrum are generally unknown in nature. There is a need for true spectrum …

Cognitive radio (CR) is a novel technology that allows to improve spectrum utilization by
enabling opportunistic access to the licensed spectrum band by unlicensed users [2]. This is …

Spectrograms are an essential time-frequency representation tool that has been used to
address several important problems in wireless communication systems. However, most …

Phase Shift-Keying (PSK) modulation has been applied widely in most of the data
communication system nowadays due to its noise immunity and bandwidth efficiency …
