Timing jitter is a major issue in very high speed OFDM systems, which causes serious impairments that, degrades the performance of overall system. In order to reduce the effect caused by timing jitter, here in this proposal, we introduced a novel scheme that reduces the noise caused by the effect of timing jitter by using integral oversampling under different channel environments such as AWGN, ...

The effect of signal dependent jitter noise on channel capacity is investigated. Upper and lower bounds on capacity are computed numerically for channels with a mix of signal dependent jitter noise and additive white Gaussian noise. The resulting bounds allow for comparison of potential coding gain for differing amounts of jitter noise and varying code rates. The comparison provides insight int...

This paper presents an overview of the effect of synchronisation errors on MCCDMA performance in downlink communications. We distinguish two types of synchronisation errors: carrier phase errors and timing errors. We show that the MC-CDMA system is very sensitive to a carrier frequency offset or a clock frequency offset. For a maximal load, carrier phase jitter and timing jitter give rise to a ...

We consider behaviors of output jitter in the simplest spiking model, the integrate-and-fire model. The full spectrum of behaviors is found: The output jitter is sensitive to the input distribution and can be a constant, diverge to infinity, or converge to zero. Exact formulas for the convergence or the divergence of output jitter are given. Our results suggest that the exponential distribution...

We evaluate the variation of inter-cell arrival times, namely jitter, as seen by a workstation. We present experimental results of actual jitter measurements on the FORE ASX200BX switch and a Pentium workstation running Linux. We analyze how the ATM network card device driver on a workstation perceives the jitter introduced by the network. We conclude from our data that the cell clumping that t...

In this paper, we investigate the influence of the carrier phase jitter of a phase-locked local oscillator on the performance of a multi-carrier code-division multipleaccess (MC-CDMA) system in a non-dispersive channel. This carrier phase jitter degrades 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...

A new method for predicting timing jitter caused by device noise in current-mode logic (CML) frequency dividers is presented. Device noise transformation into jitter is modeled as a linear time-varying (LTV) process, as opposed to a previously published method, which models jitter generation as a linear time-invariant (LTI) process. Predictions obtained using the LTV method match jitter values ...

This article proposes a jitter-aware decoupling capacitors placement optimization method that uses the genetic algorithm (GA). A novel for defining target function in regard to power delivery network (PDN) and source-induced jitter (PSIJ) based on GA-based tool is proposed. The proposed can provide an optimum economic solution number of use PDN reach impedance. Then, by modifying with our metho...

Multimedia applications have the potential to enhance work for teams of users collaborating across distances. Jitter hampers the e ectiveness of these multimedia applications. Jitter is the variation in the end-to-end delay of data sent from one user to another. Jitter can cause silent gaps in the playout of an audio stream such as in an audioconference, or a choppy appearance to a video stream...
