This paper presents a novel deep-learning (DL)-based approach for classifying digitally modulated signals, which involves the use of capsule networks (CAPs) together with the cyclic cumulant (CC) features of the signals. These were blindly estimated

Abstract This paper presents a novel method for enabling communication in cyclostationary interference limited environments by adaptively inserting and exploiting spectral redundancy in an orthogonal frequency division multiplexing (OFDM) signal. The

Challenges in interference-limited satellite detection arising from the low-earth orbit (LEO) and the Industrial, Scientific and Medical (ISM) frequency bands are addressed. In particular, a novel signal presence detector based on cyclostationary sig

This paper presents a novel filter for mitigating the interference of pulsed chirp radar signals to orthogonal frequency-division multiplexing (OFDM) signals, reducing the size of exclusion zones or dependence on spectrum access systems. The method e

The problem of detecting the presence of Gaussian frequency-shift keying (GFSK) modulated low-earth-orbit small-satellite signal in the Industrial, Scientific, and Medical (ISM)-band at 914 MHz is considered. Challenges imposed by the communication l

We sketch the components of a system designed to compete in the Battle of the ModRecs Workshop at DySPAN 2017. The core ideas are the use of a flexible channelized receiver for obtaining the complex envelopes of variable-bandwidth bands-of-interest a

Dynamic spectrum sharing paradigm is envisaged to meet the growing demand for the Radio Frequency (RF) spectrum. There exist several technical, regulatory, and business impediments for adopting the new paradigm. To address these challenges, we need t

The radio frequency (RF) spectrum has been observed to be underutilized in the space, time, and frequency dimensions. To improve its utilization and meet growing demand, dynamic spectrum-sharing models are being investigated. In order to maximize the

Previous studies on the cyclostationarity aspect of orthogonal frequency division multiplexing (OFDM) and single carrier linearly digitally modulated (SCLD) signals assumed simplified signal and channel models or considered only second-order cyclosta
