In this paper, a distributed Unscented Kalman Filter method (UKF) based on improved joint probabilistic data association (IJPDA) is proposed to solve the problem of nonlinear state estimation on multi-sensor multi-target tracking. Firstly, IJPDA method is introduced which determines the source of the multi-sensor data to simplify calculation complexity. Then the distributed UKF algorithm is presented...
As the amount of crimes involving the digital dimension grows, an ever increasing number of digital artifacts collected from a forensic investigation needs plenty of resources to process in a forensically sound manner. Digital forensic triage provides a way to deal with this scalability problem, as it is tailored to maximize the utilization of resources based on a priority system. Unfortunately, the...
A 330,000 gate field programmable gate array (FPGA) VS12C fabricated on 0.2μm full-depletion silicon-on-insulator (FD SOI) process is presented and the test results indicate this chip has the lower power and higher tolerance to radiation compared with Xilinx radiation-hardened XQVR300 chip implemented on 0.22μm epitaxial silicon. This paper demonstrates the benefit of the FD SOI technology on low...
In this paper, an ultra-wideband low-noise-amplifier (LNA) is designed for low-voltage and multi-standard applications in 0.13 μm CMOS technology. Based on conversional resistive-negative-feedback structure, a novel feedback inductor technology is proposed. The presented LNA achieves a voltage gain of 14.7 dB, 2.95-4.1 dB noise figure from 0.5-10.6 GHz including test buffer. And the IIP3 is -7.2dBm...
At present, in most RFID systems, data acquisition and system configuration of mobile readers are based on site collection and then synchronization of data and configuration information with server by manual work. Because of extensive application of RFID systems, it may become the critical system of consumer payment, identification and many other service applications. However, data synchronization...
At mm-wave frequency, the layout of CMOS transistors has a larger effect on the device performance than ever before in low frequency. In this work, the distance between the gate and drain contact (Dgd) has been enlarged to obtain a better maximum available gain (MAG). A 0.6 dB MAG improvement is realized when Dgd changes from 60 nm to 200 nm. By using the asymmetric-layout transistor, a four-stage...
This paper presents a 10-bit 40-MS/s pipelined ADC in a 0.13-μm CMOS process for subsampling applications. A simplified opamp-sharing scheme between two successive pipelined stages is proposed to reduce the power consumption. For subsampling, a cost-effective fast input-tracking switch with high linearity is introduced to sample the input signal up to 75 MHz. A two-stage amplifier with hybrid frequency...
Mobile networks, in particular the emergence of 3G networks, value-added network services will be brought some new opportunities. Electronic card as value-added services will be more room for development. We design and implement an electronic card system with a combination of the mobile network and the Internet. Users can access it through three ways (web, wap, and sms) to conduct electronic card...
The resource sharing of wireless sensor networks (WSNs) under the Internet environment is one of the key issues to be solved for the application of WSNs. It proposed a Web Services based sensor network architecture, which can enlarge the application domain and increase the scalability and maintenance of current solutions. In the scheme, users can conveniently access WSNs via web browser at anytime...
