Spectral testing and linearity testing are two important categories in ADC testing. The sampling clock quality is a crucial factor in ADC spectral testing. The cumulative clock jitter of the sampling clock generates power leakage in the fundamental component of the ADC output spectrum, and the random clock jitter increases the noise floor of the ADC output spectrum, which corrupts the spectrum result...
This paper analyzes and compares the frequency responses of both Cu based interconnect and heterogeneous interconnect which consists of graphene sheets and Cu. By using partial element equivalent circuit (PEEC) method, the equivalent electric parameters of these two kinds of interconnects are obtained. A driver-interconnect-load (DIL) model and an equivalent single conductor (ESC) circuit are utilized...
This paper observes that a number of new methods have emerged for efficient and effective testing of data converters, but there is no work comparing their strengths and weaknesses. The authors describes recent methods in detail, highlighting important aspects and contrasting their abilities to perform various test measurements.
In this paper we present a practical approach to relative positioning of heterogeneous mass market devices. We propose a user-centric solution exploiting measurements from on-the-fly fixed reference points detected during scanning procedures. The technique implemented on mobile devices is able to locate neighboring nodes, demonstrating to be a feasible and practical solution for sensing spatial social...
Industrial cluster is essentially an economic subsystem, from the perspective of system the performance of Fuyang paper industrial clusters is reflected in such five areas as economic promotion, competition level, output capacity, cooperation level, industrial cluster, In this paper builds on the Fuyang paper industrial cluster performance evaluation, And fuzzy evaluation method used to quantify the...
The notion of identity-based online/offline encryption (IBOOE) was recently introduced by Guo, Mu and Chen in FC 2008. In an IBOOE system, the encryption is split into online and offline phases. The offline phase is performed prior to the arrival of a message and the recipient's public key (or,identity). The online phase is performed very efficiently after knowing the message and public key. The IBOOE...
Topology control is an effective measure at network layer to implement power control for energy-saving, which is a critical issue in ad-hoc wireless networks. Topology control also affects other significant performances of network, such as packet delivery radio, end-to-end delay, and network capacity etc. Various techniques and algorithms have been proposed to achieve the optimal topology which can...
Malicious nodes in a mobile and wireless ad hoc network can be a threat to the security and/or anonymity of the exchanged data. While data encryption can protect the content exchanged between nodes, routing information may reveal the identities of communicating nodes and their relationships. This paper describes our effort to provide anonymous communication services in mobile and wireless ad hoc networks...
