	abstract = {This paper proposes new accurate approximations for average error probability (AEP) of a communication system employing either M-phase-shift keying (PSK) or differential quaternary PSK with Gray coding (GC-DQPSK) modulation schemes over generalized fading channel. Firstly, new accurate approximations of error probability (EP) of both modulation schemes are derived over additive white Gaussian noise (AWGN) channel. Leveraging the trapezoidal integral method, a tight approximate expression of symbol error probability for M-PSK modulation is presented, while new upper and lower bounds for Marcum Q-function (MQF) of the first order, and subsequently those for bit error probability (BEP) under DQPSK scheme, are proposed. Next, these bounds are linearly combined to propose a highly refined and accurate BE P{\textquoteright}s approximation. The key idea manifested in the decrease property of modified Bessel function Iv, strongly related to MQF, with its argument v. As an application, these approximations are used to tackle AEP{\textquoteright}s approximation under κ - {\textmu} shadowed fading. Numerical results show the accuracy of the presented approximations compared to the exact ones. {\textcopyright} 2021 Institute of Electrical and Electronics Engineers Inc.. All rights reserved.},

	abstract = {Spectrum scarcity is the principal motivation behind the development of cognitive radio. This technology introduces new functionalities at the physical, medium access control, and network layers of the TCP/IP protocol stack. These functionalities can be subject to new security threats. Most of the existing works in cognitive radio focused on the security issues in both the physical and medium access control layers. However, threats related to the network layer have not been studied despite its importance in establishing communication between different users in cognitive radio networks. In this paper, we classify and give an overview of attacks that target the network layer functionalities of cognitive radio networks. We discuss the existing detection techniques and countermeasures and highlight the main security challenges for such networks. {\textcopyright} 2017 Elsevier Ltd},

	abstract = {Multiple-input multiple-output (MIMO) systems play a great role in improving performance of wireless communication system and are commonly used to ensure high bit-rate transmission. Space-time block codes (STBC) are a remarkable modulation scheme discovered recently for the multiple antenna wireless channel. They have an elegant mathematical solution for providing full diversity over the coherent, flat-fading channel. In this paper, a method for approximating the probability distribution of sum of independent and identical Weibull random variables is adopted to derive a tight analytical expressions for various performance criteria of STBC{\textquoteright}s coding operating under identical and independent Weibull fading channels (WFC). The proposed Analytical expressions are given in terms of simple, gamma and Fox-H functions. These expressions demonstrate the best fit to simulation results using Monte-Carlo simulation and other statistical methods. {\textcopyright} 2016 IEEE.},

	abstract = {This paper presents tighter bounds on the pairwise error-event probability and therefore very tighter upper bounds of bit error rate(BER) for communication systems employing convolutional code over Rayleigh fading channel with exponential correlation coefficient. To obtain our bound, we start by proposing a closed form upper bound for Gaussian Q-function and as well as deriving a new lower bound of each channel covariance matrix eigenvalue. The simulation results show that our proposed bound is tighter than those previously developed, especially when the covariance parameter q increases. A gain of over 6.5dB was achieved for q = 0.95 at BER=10-5 from the better previous bound, whereas for the lower values of q we reach the simulated curve. {\textcopyright} 2016 IEEE.},
