For more information, see Getting Started with Object Detection Using Deep Learning (Computer Vision Toolbox). Our aim is to minimize the accuracy of the intruder, while Formally, the modulated signal x is obtained as x=Ms(w) where s∈S is the employed modulation scheme with S denoting the set of available modulation schemes, and for any s, Ms:{0,1}m→Cn denotes the whole encoder function with modulation s. We assume that Ms satisfies the power constraint (1/n)∥x∥22≤1 for any data w. After encoding, the signal x is sent over a noisy channel, assumed to be an additive white Gaussian noise (AWGN) channel for simplicity: the baseband signals y1 and y2, received by the receiver and the intruder, respectively, are given by, where z1,z2∈Cn are independent realizations of the channel noise (also independent of x, ) with independent zero-mean complex Gaussian components with variance. As the classifier, we apply the same deep CNN architecture as [6] for the intruder, Following the idea of adversarial attacks on image classifiers [9], an idealized adversarial attack to the classifier fθ of the intruder would modify a correctly classified channel output sequence y2 (i.e., for which s=fθ(y2)) with a perturbation δ∈Cn such that fθ(y2+δ)≠fθ(y2), the true label. Experimental results on synthetic problems verify the viability of our approach by showing that our methods are able to substantially reduce the modulation classification accuracy of the intruder with minimal sacrifice in the communication performance.

Specifically, deep. If the maximum is 1, such a δ results in a successful adversarial perturbation and a successful adversarial example y2+δ (i.e., one for which the intruder makes a mistake), while the BER is likely still small. This second edition focuses on audio, image and video data, the three main types of input that machines deal with when interacting with the real world.

In every case, DMS trades off increased BER for reduced detection accuracy compared to the no-defense case. ∙ For network design guidance, see Deep Learning Tips and Tricks. Our goal in this paper is to modify the encoding processes Ms such that, given a modulation scheme s∈S, the new encoding method M′s ensures that the intruder’s success probability gets smaller, while the BER of the receiver (using the same decoding procedure for Ms) does not increase substantially.

To further improve the security, encryption can be complemented with other techniques, preventing the adversary from even recovering the encrypted bits. However, its usage in communication systems has not been well explored. Clock offset, resulting in center frequency offset and sampling time drift.

Several learning-based signal detectors have been proposed to produce significant results. 0 Since BDMS depends on the weighting coefficient λ, results for multiple λ values are presented. Before we can use a CNN for modulation classification, or any other task, we first need to train the network with known (or labeled) data.

This paper presents channel-aware adversarial attacks against deep intercepted signal. Formally, the aim of the intruder is to determine, for any sequence of channel output symbols y2∈Cn, the modulation method used by the transmitter. All the above schemes, except for DMSU, are implemented using the projected (normalized) gradient descent (PGD) [12] method from the CleverHans Library [16], with 20 iterations, β=0.2 and ϵ=3. Modulation classification, recognized as the intermediate step between signal detection and demodulation, is widely deployed in several modern wireless communication systems. message can still be reliably decoded by the legitimate receiver which is Clock offset occurs because of the inaccuracies of internal clock sources of transmitters and receivers. In the past few years, deep learning object detection has come a long way, evolving from a patchwork of different components to a single neural network that works efficiently. Due to the large computational overhead of calculating the SPSA gradient estimates (7) (with K=400), we only used 400 signal blocks to measure the test performance (instead of the 300×20=6000 blocks used previously).

Found insideThis hands-on guide not only provides the most practical information available on the subject, but also helps you get started building efficient deep learning networks. Therefore, the modulation detection should be completed based on a short sequence of channel symbols. However, its usage in communication systems has not been well explored. The framework considers both a deep convolutional neural network (CNN) and a long short term memory network. Our aim in this paper is to prevent an intruder that employs a CNN-based modulation detector from successfully identifying the modulation scheme being used. Furthermore, since now the perturbed signal is transmitted at the actual SNR of the channel, the effective SNR of the system is decreased, as the transmitted signal already includes the perturbation δ, which can be treated as noise from the point of view of transmitting x (and not ¯x). This book is a collection of best selected research papers presented at the Conference on Machine Learning, Deep Learning and Computational Intelligence for Wireless Communication (MDCWC 2020) held during October 22nd to 24th 2020, at the ... This example uses a CNN that consists of six convolution layers and one fully connected layer. The files have two variables: frame and label and each read call to the datastore returns a cell array, where the first element is the frame and the second element is the label.

It can be seen that for large SNR (≥8dB), all defensive schemes achieve roughly the same classification accuracy (much smaller than for the no-defense case), while BODMS and BDMS for large λ provide significant improvement in the bit error rate (shown for QAM64); note, however, that the errors are still significantly higher than for the standard QAM64 modulation.

Deep learning (DL) is a powerful technique which has achieved great success in many applications. In order to do so, we maximize L(θ,¯y2,s) using stochastic PGD (again, in every step we choose independent noise realizations), but we restrict the steps in the directions where the bit error rate does not change. In the latter perturbation is limited to be imperceptible to a There is an inherent trade-off between our two targets: a larger δ results in a bigger reduction in the detection accuracy of the intruder, but will also increase the BER at the receiver, while a smaller δ results in a smaller BER but provides less protection against the intruder. ∙ In particular, deep learning (DL) demonstrates significant benefits in computer vision, robotics, and speech recognition.
