“…Additionally, the authors use the energy ratios of the perturbation and modulated signal as an attack constraint, a metric that the current work uses as well. However, the authors consider perturbations which are below the noise floor but implicitly assume they are able to 1 Black-box refers to attacks with full access to the training dataset but no knowledge of the DNN architecture of learned parameter matrices. compromise the eavesdropper's signal processing chain by not considering the effect of the channel on the perturbation signal.…”

“…One subset of RFML deals with utilizing raw in-phase and quadrature (IQ) samples for spectrum sensing. Spectrum sensing can be used in Dynamic Spectrum Access (DSA) systems to determine the presence of primary and secondary users in order to adapt transmission parameters to the environment [1] and has obvious applications to signals intelligence. Prior approaches to spectrum sensing were likelihood or feature based [2]- [7] while more recent approaches leverage the advances in deep neural networks (DNN) to operate directly on raw IQ samples [8]- [13].…”

Recent advancements in radio frequency machine learning (RFML) have demonstrated the use of raw in-phase and quadrature (IQ) samples for multiple spectrum sensing tasks. Yet, deep learning techniques have been shown, in other applications, to be vulnerable to adversarial machine learning (ML) techniques, which seek to craft small perturbations that are added to the input to cause a misclassification. The current work differentiates the threats that adversarial ML poses to RFML systems based on where the attack is executed from: direct access to classifier input, synchronously transmitted over the air (OTA), or asynchronously transmitted from a separate device. Additionally, the current work develops a methodology for evaluating adversarial success in the context of wireless communications, where the primary metric of interest is bit error rate and not human perception, as is the case in image recognition. The methodology is demonstrated using the well known Fast Gradient Sign Method to evaluate the vulnerabilities of raw IQ based Automatic Modulation Classification and concludes RFML is vulnerable to adversarial examples, even in OTA attacks. However, RFML domain specific receiver effects, which would be encountered in an OTA attack, can present significant impairments to adversarial evasion.

“…Spectrum sharing technologies have significantly advanced since Mitola introduced the concept of cognitive radio in [1]. Dynamic spectrum access technologies are already included in multiple standards in different frequency bands, and regulatory processes are being updated to include new forms of licensing [2]. Coordinated spectrum sharing approaches are being developed and proposed between different technologies used in the industrial, scientific and medical (ISM) bands [3].…”

In this paper, we describe a spectrum access system (SAS) based Citizens Broadband Radio Service (CBRS) field trial using a live LTE network in the 3.5 GHz band. The latest WInnForum specification guided the implementation of the relevant protocols for SAS operation. Here, we evaluate the performance of a CBRS field trial by using one of the most important performance indicators in a spectrum sharing scenario -the evacuation time. It indicates how rapidly the secondary user relinquishes the shared spectrum band to the primary user. Following the applied protocols, we measure and analyze the time scales for the evacuation and frequency change procedures in a field trial environment. Our work shows that the set time limits for the protection of primary users against interference are realistic when using commercially available mobile networks and equipment. Finally, utilizing knowledge of the latest base station models, we propose ways to reduce the evacuation and reconfiguration time by up to 70%.

In this demonstration proposal, we present a prototype of a rapidly deployable and cost-effective railroad crossing early warning system integrated with the railway system. Specifically, the proposed demonstration deal with the safety applications based on dedicated short range communications (DSRC) protocol and devices using our different antennas. We will demonstrate the feasibility and advantages of our proposed system, including the antenna design, system deployment, the over-the-air transmission, and the software applications that we developed for the end users 1 .I.
