Family of Nyquist-I Pulses to Enhance Orthogonal Frequency Division Multiplexing System Performance
(Taylor and Francis, 2016)
A family of Nyquist-I pulses called sinc parametric linear combination pulse (SPLCP) is proposed. It is characterized by two novel design parameters that provide additional degrees of freedom to minimize the intercarrier ...
Suppressing the effect of ICI power using dual sinc pulses in OFDM-based systems
Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
Influência da anodização pulsada nas propriedades da alumina anódica porosa (AAP)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciências dos Materiais (campus SOROCABA)Câmpus Sorocaba, 2017-04-27)
Porous anodic alumina can be obtained, in addition to conventional methods such as potentiostatic and galvanostatic, or by pulsed method. Among these are the methods of discontinuous pulse, hybrid pulse and polarized pulse ...
Improved Nyquist-I Pulses to Enhance the Performance of OFDM-Based Systems
Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...
Subsiding OOB Emission and ICI Power Using iPOWER Pulse in OFDM Systems
(Univ Suceava, Fac Electrical Eng, 2016)
A novel family of Nyquist-I pulses called iPOWER is proposed with a new design parameter. that provides an extra degree of freedom for a certain roll-off factor, a. The proposed pulse is examined and compared with other ...
Performance Enhancement of OFDM-Based Systems Using Improved Parametric Linear Combination Pulses
As the demand for better performance increases in next-generation networks, such as 5G technologies, more efficient modulation techniques are required. In this work, we evaluate the performance of the improved parametric ...
ICI Reduction in OFDM Systems Using a New Family of Nyquist-I Pulses
In this paper the parametric linear combination pulse (IPLCP) is proposed. The IPLCP is a new family of Nyquist-I pulses with two additional degrees of freedom to minimize the inter-carrier interference (ICI) power in ...
Generation of optical frequency combs via four-wave mixing processes for low- and medium-resolution astronomy
We investigate the generation of optical frequency combs through a cascade of four-wave mixing processes in nonlinear fibres with optimised parameters. The initial optical field consists of two continuous-wave lasers with ...
Drying of a Porous Material in a Pulsed Fluid Bed Dryer: The Influences of Temperature, Frequency of Pulsation, and Air Flow Rate
(Taylor & Francis IncPhiladelphiaEUA, 2009)
Frequencies of virulence genes and pulse field gel electrophoresis fingerprints in Escherichia coli isolates from canine pyometra
(Elsevier B.V., 2014-11-01)
Escherichia coli is the most common bacterial agent isolated from canine pyometra. The frequencies of 24 virulence genes and pulsed field gel electrophoresis (PFGE) profiles were determined for 23 E. coli isolates from ...
