On numerical design technique of wideband microwave amplifiers based on GaN small-signal device model
(Springer, 2014-10)
This work presents an application of Normalized Gain Function (NGF) method to the design of linear wideband microwave amplifiers based on small-signal model of a device. NGF has been originally developed to be used together ...
Optimizing circular ring arrays for forward-looking IVUS imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2011-12)
Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) applications. One of the main challenges of array-based FL-IVUS systems is the large ...
Algebraic break of image ciphers based on discretized chaotic map lattices
(Elsevier Science Inc, 2011-01-01)
In this paper, we provide an algebraic cryptanalysis of a recently proposed chaotic image cipher. We show that the secret parameters of the algorithm can be revealed using chosen-plaintext attacks. Our attack uses the orbit ...
Student conference as a student centred environment for integrating technical writings into computer engineering curriculum
(Anı Yayıncılık, 2011-12)
Problem Statement: In today's world there are pressures on universities to ensure that graduates have the capacity to meet the needs of employers. One aspect of this is to ensure that students, along with professional ...
An analysis of stability of uncertain neural networks with multiple time delays
(Pergamon-Elsevier Science Ltd, 2013-09)
This paper deals with the problem of robust stability of neural networks with multiple time delays with the class of unbounded and nondecreasing activation functions. By constructing a suitable Lyapunov functional and ...
A low complexity modulation classification algorithm for MIMO systems
(IEEE-INST Electrical Electronics Engineers Inc, 2013-10)
A novel algorithm is proposed for automatic modulation classification in multiple-input multiple-output spatial multiplexing systems, which employs fourth-order cumulants of the estimated transmit signal streams as ...
Cyclostationarity-based robust algorithms for QAM signal identification
(IEEE-INST Electrical Electronics Engineers Inc, 2012-01)
This letter proposes two novel algorithms for the identification of quadrature amplitude modulation (QAM) signals. The cyclostationarity-based features used by these algorithms are robust with respect to timing, phase, and ...
An eclectic approach to design tunable amplifiers
(Wiley-Blackwell, 2013-07)
Broadband amplifiers that can accommodate commercial communication standards such as GSM, UMTS, Wi-Fi, and Wi-Max are extremely important for radio equipment manufacturers. To achieve this coverage, the amplifier should ...
High precision LC ladder synthesis part ıı: Immittance synthesis with transmission zeros at DC and infinity
(IEEE-INST Electrical Electronics Engineers Inc, 2013-10)
In this paper, a novel, high precision bandpass LC ladder synthesis algorithm is presented. The new algorithm directly works on the rational form of a positive real driving point input immittance F(p) = a(p)/b(p) which ...
Re-mining item associations: Methodology and a case study in apparel retailing
(Elsevier Science BV, 2011-12)
Association mining is the conventional data mining technique for analyzing market basket data and it reveals the positive and negative associations between items. While being an integral part of transaction data, pricing ...
