In recent years, Smart grid has drawn much more attention because of improving environmental consciousness and $3.4 billion funding from the Obama Administration in the United States. A reliable communication network is the core of smart grid. This paper addresses the communication demand of constructing smart grid. Various communication technologies are discussed, including wired and wireless technologies...
This paper presents a wireless distributed system to measure transient electromagnetic field in power substations. Taking advantage of flexible short-range wireless technique, the system allows flexible multi-node simultaneous measurement while is of compact size and low cost.
The raising cost of the latest technology nodes as well as the design cost associated has motivated an increasing push for flexible radio implementations. In this context, Sigma-Delta (SigmaDelta) ADCs have emerged as a promising alternative to direct conversion. In this work a novel wireless receiver architecture based on an RF bandpass SigmaDelta is considered. One of the key blocks of this architecture...
Complex signal processing algorithms are often specified in floating point precision. Thus, a type conversion is needed when the targeted platform requires fixed-point precision. In this work we proposed a new method to evaluate the final impact of finite precision processing in wireless applications. The latter combines analytical analysis with simulations. This extends previous work including the...
Micro operation assisted by miniature mobile robot system has become a research hot in robotics and micro operation domain. In this paper, a newly developed micro operation oriented five D.O.F. (degrees of freedom) miniature mobile robot system is presented. By comparing it with other miniature robot systems, the main improvements of this design are macro/micro dual driven, embedded hardware, wireless...
