A reconfigurable full-metal-rimmed MIMO antenna is designed and proposed for WWAN/LTE smartphones. This antenna consists of two centro-symmetrically distributed antenna elements and radiation structures using the unbroken metal rim in plastic casing. It can achieve a good isolation of more than 17dB over the entire operation bands. Each antenna element occupies a small ground area of $30\times 6$ ...
An optoelectronic oscillator (OEO) tuned from 4.74 GHz to 38.38 GHz is proposed and experimentally demonstrated. To our knowledge, this is the widest fundamental frequency tunable range achieved by an OEO.
Depth map prediction is the key point in Free Viewpoint Video technique. Among current depth map estimation approaches, combined temporal and interview prediction method is the most practical one for hardware design and real time processing. It is based on block search inter-prediction on various block size to get the best estimation result with specific cost function. Although much data processing...
With increasing dependency on communication systems, finite communication bandwidth has become the bottleneck of networked control system (NCS). Research on NCS is not only concerned about control system but also communication networks. Control and scheduling co-design is a feasible way to solve this bottleneck problem in NCS which aims to ensure both quality of performance (QoP) and quality of service...
More and more complex application cases bring much heavy bandwidth loading problem to SoC architecture. To design a high performance SoC system which supports large amount and high speed data processing capability, an efficient, systematic, and quick performance evaluation of SoC architecture becomes the base requirement for chip success. A novel performance evaluation method based on memory access...
Scalability considerations drive the evolution of switch design from output queueing to input queueing and further to combined input and crosspoint queueing (CICQ). However, CICQ switches with credit-based flow control face new challenges of scalability and predictability. In this paper, we propose a novel approach of rate-based smoothed switching, and design a CICQ switch called the smoothed buffered...
