“…For example as it is illustrated in Figure 1, the non-cooperative users in the CIC can be modeled in base stations (as the transmitters) which are controlled via SDN. 3 Base stations intend to send messages to their related receivers. The cognitive base station may execute the SDN controller commands and cooperate to transmit other base station's messages or may act selfishly to send its related receiver's messages.…”

“…The concepts of software defined network (SDN) and network function virtualization (NFV) are candidate techniques to this end. The SDN/NFV architecture is potential to enable spectrum usage with the cognitive radio techniques in the next generation communication 2,3 . Hence, the cognitive radio technology which is a solution to improve the spectral efficiency due to the increase of wireless services, has an important role in 5G.…”

In this paper, we have combined a game-theoretic and an information-theoretic notions to describe the selfish behavior of each user in a two-user linear deterministic cognitive interference channel (LD-CIC). The two-user LD-CIC is the simple case of the cognitive radio technology in the high SNR regime. This model is a solution to improve the spectral efficiency in software defined network (SDN) concept in 5G. In the two-user LD-CIC, the information bits of the primary/licensed transmitter is a-priori provided at the cognitive/secondary/unlicensed transmitter. So that, the cognitive transmitter can cooperate and utilize the frequency spectrum to send the information bits of the both transmitters. In information-theoretic approaches, full cooperation is assumed between transmitters for codebook and rate selection in this channel.

“…In the last few decades, a number of applications, including cognitive radio [1,2], signal monitoring [3,4], and signal interception [5], have garnered a lot of attention due to the rapid expansion of wireless communication. In these applications, the use of automatic modulation classification (AMC) to identify modulation types without sufficient a priori knowledge has become a crucial step between signal detection and signal demodulation.…”

A symmetric adaptive visibility graph classification method of orthogonal signals for automatic modulation classification

et al. 2023

Visibility graph methods allow time series to mine non‐Euclidean spatial features of sequences by using graph neural network algorithms. Unlike the traditional fixed‐rule‐based univariate time series visibility graph methods, a symmetric adaptive visibility graph method is proposed using orthogonal signals, a method applicable to in‐phase and quadrature (I/Q) orthogonal signals for adaptive graph mapping for radio modulated signals in automatic modulation classification tasks. The method directly models the intra‐channel and inter‐channel graph relations of I/Q signals using two different types of convolutional kernels. It captures non‐Euclidean spatial feature information of I/Q signals using a graph neural network combining graph sampling aggregation and graph differentiable pooling as a feature extractor. Extensive experimental results on two benchmark datasets and a simulated dataset containing channel fading show that the proposed Quadrature Signal Symmetric Adaptive Visibility Graph (QSSAVG) method in this paper outperforms the benchmark method in terms of classification accuracy and is also more robust against channel fading and noise variations.
