This work investigates how stochastic unmeasurable sampling jitter noise affects the result of system identification, and proposes a modification of known approaches to mitigate the effects of sampling jitter. By just assuming conventional additive measurement noise, the analysis shows that the identified model will get a bias in the transfer function amplitude that increases for higher frequen...

We address the problem of integrating real-time fault-tolerance mechanisms into peer-to-peer systems, with specific architecture and deployment constraints. For this purpose we implemented a prototype hierarchical peer-to-peer framework in which the leaf peers are sensors that generate different kinds of traffic such as mesh management, events, video and audio. We evaluate the framework by meas...

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...

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 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...

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...

The performance of real time applications such as video and voice streams relies on packet delay jitter. Large delay jitter causes buffer overflow or underflow at the receiver end and the user encounters interrupts. The delay jitter is mainly due to the perturbation of background traffic in the bottleneck router. Fulton and Li 1121 provide an analytical approximation for the tirst-order and sec...

With high bandwidth demand in the telecommunication and networking area, low voltage and low jitter Phase Lock Loop (PLL) is becoming of utmost importance. As the data rate becomes faster, the total jitter budget gets smaller. For instance, an OC-192 transceiver compliant is allowed less than 1ps of total jitter due to random noise (rms jitter) and a maximum of 10ps for the deterministic jitter...

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...
