Improving the Performance of LP Decoders for Cyclic Codes
2009 IEEE International Conference on Communications, 2009Recently, a linear programming (LP) decoder has been introduced for binary linear codes. Although the performance of an LP decoder has a close relationship with the form of the parity check matrix (or equivalently with the Tanner graph) of the code, there is no clear approach to choosing a suitable form for LP decoding.

Signal interception: performance advantages of cyclic-feature detectors
IEEE Transactions on Communications, 1992The problem of detecting the presence of spread-spectrum phase-shift-keyed signals in variable noise and interference backgrounds is considered, and the performances of four detectors are evaluated and compared. The detectors include the optimum radiometer, the optimum modified radiometer that jointly estimates the noise level and detects the signal ...

Performance of Cyclic Delay Diversity in Ricean Channels
2007Cyclic delay diversity (CDD) provides additional diversity in Rayleigh fading channels, and therefore, improves system performance. For line-of-sight (LOS) propagation, e.g. the additive white Gaussian noise channel, the implementation of CDD yields to a performance loss.

The cyclic fatigue of high-performance fibers
JOM, 2005High-performance fibers are virtually ubiquitous in our everyday lives. In a variety of structural applications, fibers and fiber-reinforced composites are subjected to cyclic mechanical loading. This paper reviews the fatigue behavior of some common high-performance fibers such as polymer, metal, and ceramic fibers.

Performance evaluation of cyclic polyspectrum estimators
[1992] Conference Record of the Twenty-Sixth Asilomar Conference on Signals, Systems & Computers, 2003Results of analysis and computer simulations are used to compare two methods of estimating the cyclic polyspectrum. The computational requirements of the two methods are determined and compared. A cycle leakage phenomenon is explained and it is shown that, for a given amount of data, only one of the two methods can be modified to reduce this leakage ...

Filter Performance with Cyclic Flow
SAE Technical Paper Series, 1986<div class="htmlview paragraph">A multipass test bench was used to illustrate the effects of variable flow on particle retention and provide a non-mathematical picture of this complex phenomenon. The relative influence of the duty cycle, the amount of dirt in the element, and the efficiency and physical makeup of the media provide a qualitative ...

On the Performance of Cyclically Adjusted Valuation Measures
SSRN Electronic Journal, 2013We confirm the effectiveness of using cyclically-adjusted valuation metrics to identify high performing stocks. The Shiller P/E, or cyclically-adjusted price-to-earnings (CAPE) ratio, is not the optimal way to implement a cyclically-adjusted value measure.

Performance model of cyclic processes
Technical Transactions. Fundamental Sciences = Czasopismo Techniczne. Nauki Podstawowe, 2010This paper presents the use of both Petri nets and max-plus algebra formalism for modeling dynamic behaviour of system with cyclic processes. A cyclic processes system contains elements, which can operate in parallel while at the same time. They can have cooperative and competitive relationships.

An analysis of combined cyclic heat treatment performance
Journal of Materials Processing Technology, 2004The strengthening of AISI 4140 steel by cyclic heat treatment has been investigated. The applied cyclic heat treatment was consisted of both, temperature cycling with diffusional transformation and double quenching with diffusionless transformation.

Cyclic Performance of Composite Bracing Members
2011In seismic regions, steel tubular bracing members have widely been used in steel structures. Although there are some shortages with such systems, due to their economical advantages, they are being used in many structures. The steel hollow brace members exhibit stable hysteretic behavior up to the point of first local buckling, and subsequently they ...
