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 ...
Analysis and design of low-cost bit-serial architectures for motion estimation in H.264/AVC
(Springer, 2013-05)
Variable block-size motion estimation (VBSME) process occupies a major part of computation of an H.264 encoder, which is usually accelerated by bit-parallel hardware architectures with large I/O bit width to meet real-time ...
Colored simultaneous geometric embeddings and universal pointsets
(Springer, 2011-07)
Universal pointsets can be used for visualizing multiple relationships on the same set of objects or for visualizing dynamic graph processes. In simultaneous geometric embeddings, the same point in the plane is used to ...
Breaking an orbit-based symmetric cryptosystem
(Pergamon-Elsevier Science Ltd, 2011-09)
We report a break for a recently proposed class of cryptosystems. The cryptosystem uses constant points of a periodic secret orbit to encrypt the plaintext. In order to break the system, it suffices to sort the constant ...
On the second-order cyclic statistics of signals in the presence of receiver impairments
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)
Cyclostationary characteristics of communication signals can be exploited for performing various signal processing tasks. Receiver impairments that affect the cyclic statistics of signals may lead to a degradation in the ...
Omnivariate rule induction using a novel pairwise statistical test
(IEEE Computer Soc, 2013-09)
Rule learning algorithms, for example, RIPPER, induces univariate rules, that is, a propositional condition in a rule uses only one feature. In this paper, we propose an omnivariate induction of rules where under each ...
Model selection in omnivariate decision trees using Structural Risk Minimization
(Elsevier Science Inc, 2011-12-01)
As opposed to trees that use a single type of decision node, an omnivariate decision tree contains nodes of different types. We propose to use Structural Risk Minimization (SRM) to choose between node types in omnivariate ...
