A simplified overview of time-domain jitter measurements is presented in this paper. The relationship between the timedomain jitter measurements and the power spectrum of the phase jitter is described using fundamental Fourier properties and basic random variables analysis. This leads to a unifying analysis and the results are in agreement with commonly accepted understanding of jitter accumula...
هدف: فلج یکطرفه تارآواها و پولیپ، منجر به ناقرینگی تارآواها میشوند. هدف این مطالعه بررسی تغییرات احتمالی پارامترهای آکوستیکی در این اختلالات و مقایسه آنها با دادههای افراد سالم است. روش بررسی: پژوهش حاضر مقطعی و توصیفی تحلیلی است. آزمودنیها شامل 5 بیمار مبتلا به فلج یکطرفه تارآواها و 5 بیمار مبتلا به پولیپ بودند که به طور غیرتصادفی از میان مراجعهکنندگان به بیمارستان حضرت رسول اکرم تهران...
Data traversing packet networks experience varying delays, resulting in inter-arrival jitter. This can result in degraded performance in real-time multimedia communications applications if the jitter delays are large or unaccounted for in the receiver application. This paper examines modeling and simulation of network jitter delay for real-time multimedia communications applications. We examine...
This paper presents a novel mixed-signal verification methodology for jitter tolerance in highspeed serial-link receiver designs. The predictive approach includes identifying the jitter sources at the receiver input, generating the artificial jitter to add on input data and clock, and investigating the jitter sensitivities inside the receiver with bit error indicator. Both an artificial jitter ...
Satellite jitter has become a more and more important factor which affects the quality of imagery products with development of the high resolution satellite. This paper focused on analyzing the impact on multi-spectral image caused by satellite jitter and proposed a jitter detection and compensation method to improve the band-to-band registration efficiently when jitter exists without observati...
In this paper, we investigate the influence of carrier phase jitter on the performance of an OFDM/CDMA system. This carrier phase jitter reduces the performance of the system, defined as the signal-to-noise ratio at the input of the decision device. When all users have the same power level and phase jitter spectrum, it is shown that for the highest load, the degradation only depends on the jitt...
Multimedia streaming transmission might be affected by jitter – short term packet delivery delay variation. To avoid transmission errors there are de-jitter buffers used, therefore it is necessary to estimate the current jitter although it is impossible to calculate straight value on-line. The situation is complicated by various jitter causes and its appearances. In the paper authors propose th...

In this contribution, we consider the effect of carrier phase jitter on the performance of uplink OFDMA, uplink multicarrier CDMA (MC-CDMA) and uplink multicarrier direct sequence CDMA (MC-DS-CDMA) systems, assuming orthogonal spreading sequences. For this aim, it is proposed, first to consider a small random jitter, then, to model phase jitter by Gaussian and Rayleigh laws. Theoretical express...
Jitter significantly limits the maximum achievable data rates (MADR) over high-speed source-synchronous I/O links. In this paper, we present a simple model that comprehends transmitter and receiver jitter in a source-synchronous I/O link. We show that the channel can have a significant impact on transmit jitter at high data rates, resulting in 1.1X3.8X jitter amplification for typical cases. We...
