Power optimization algorithm based on XNOR/OR logic
Journal of Electronics (China) - Tập 26 - Trang 138-144 - 2009
Pengjun Wang, Jingang Lu, Jian Xu, Jing Dai
Based on the investigation of the XNOR/OR logical expression and the propagation algorithm of signal probability, a low power synthesis algorithm based on the XNOR/OR logic is proposed in this paper. The proposed algorithm has been implemented with C language. Fourteen Microelectronics Center North Carolina (MCNC) benchmarks are tested, and the results show that the proposed algorithm not only sig... hiện toàn bộ

An efficient approach for DVB-H handover in DVB-H/UMTS hybrid networks
Journal of Electronics (China) - Tập 25 - Trang 689-696 - 2008
Cong Liu, Jianxin Liao, Xiaomin Zhu, Huiyuan Zhang, Ping Ni
Handover in Digital Video Broadcasting for Handhelds (DVB-H) aims to provide continuous mobile broadcasting services when a user is traveling through cell boundaries. A good handover control can improve the power efficiency and gain much better reception quality. This letter provides a novel approach for DVB-H handover based on DVB-H/Universal Mobile Telecommunications System (UMTS) hybrid network... hiện toàn bộ
Nghiên cứu về cảm biến vi sóng thụ động trong việc phát hiện ô nhiễm dầu trên bề mặt biển Dịch bởi AI
Journal of Electronics (China) - Tập 14 - Trang 39-44 - 1997
Lei Zhendong, Wang Lei
Bằng cách sử dụng mô hình hệ thống không khí-dầu-bề mặt biển, ảnh hưởng của độ dày màng dầu, tần số hoạt động của máy đo bức xạ và góc chiếu sáng đến độ phát xạ hiệu quả được tính toán và phân tích. Một phương án tối ưu cho cảm biến vi sóng thụ động trong việc phát hiện ô nhiễm dầu trên bề mặt biển cũng được đề xuất và sử dụng thành công trong các thí nghiệm cảm biến vi sóng trên không.

An efficient UE cluster head selection algorithm in wireless sensor networks and cellular networks
Journal of Electronics (China) - Tập 30 - Trang 57-65 - 2013
Shan Lianhai, Yuling Ouyang, Zhi Yuan, Weidong Fang, Honglin Hu
Wireless Sensor Networks (WSNs) have been applied in many different areas. Energy efficient algorithms and protocols have become one of the most challenging issues for WSN. Many researchers focused on developing energy efficient clustering algorithms for WSN, but less research has been concerned in the mobile User Equipment (UE) acting as a Cluster Head (CH) for data transmission between cellular ... hiện toàn bộ
Random forest for intermediate descriptor fusion in shot boundary detection
Journal of Electronics (China) - Tập 31 - Trang 465-472 - 2014
Lei Zhang, Anqi Chang, Xuezhi Xiang
Shot boundary detection is the fundamental part in many real applications as video retrieval and so on. This paper tackles the problem of video segment obtaining in complex movie videos. Firstly, intermediate descriptor is proposed to depict the variation of both abrupt and gradual change in shot boundaries, which is formed by distance vector on Local Binary Pattern (LBP), GIST (GIST) or their fus... hiện toàn bộ

Novel two-layer motion estimation for video coding
Journal of Electronics (China) - Tập 31 - Trang 354-365 - 2014
A. V. Paramkusam, V. S. K. Reddy
In this paper, we proposed a novel Two-layer Motion Estimation (TME) which searches motion vectors on two layers with partial distortion measures in order to reduce the overwhelming computational complexity of Motion Estimation (ME) in video coding. A layer is an image which is derived from the reference frame such that the sum of a block of pixels in the reference frame determines the point of a ... hiện toàn bộ
A new Ad Hoc routing algorithm based on minimizing the channel handoff
Journal of Electronics (China) - Tập 27 - Trang 749-755 - 2011
Jin Xie, Qi Zhu, Zongshou Li
How to improve the performance of the wireless Ad Hoc network by utilizing the spectrum resources efficiently has become a hot research topic in recent years. In this paper we propose a reactive routing algorithm that supports multiple channels to improve the performance of the Ad Hoc network based on the minimizing of the channel handoff. Our approach allocates the communication channel during th... hiện toàn bộ
Transient analysis of nonuniform transmission lines with nonlinear terminal networks
Journal of Electronics (China) - Tập 23 - Trang 428-432 - 2006
Jinquan Zhao, Xikui Ma, Jing Xue, Guanyuan Qiu
A semi-analytical method in time domain is presented for analysis of the transient response of nonuniform transmission lines. In this method, the telegraph equations in time domain is differenced in space domain first, and is transformed into a set of first-order differential equations of voltage and current with respect to time. By integrating these differential equations with respect to time, an... hiện toàn bộ
