A real-time quantum key distribution (QKD) system is developed in this paper. In the system, based on the feature of a field-programmable gate array, secure key extraction control and algorithm have been optimally designed to perform sifting, error correction, and privacy amplification altogether in real time. In the QKD experiment, information synchronization mechanism and high-speed classic data...
This paper introduces a fast matching algorithm to reduce the computational cost of the matching phase in the correlation algorithm based cellular probe speed estimation. Real-time traffic speed is essential in current intelligent transportation systems for identifying traffic congestion and providing high quality navigation services. The correlation algorithm shows superior performance over the localization...
Real-time detection of a 40 Gbit/s polarization-multiplexed square 16-QAM signal is demonstrated in an FPGA-based intradyne coherent receiver processing 100% of data. A minimum BER of 3.3×10-5 is achieved.
Real-time polarization division multiplexed coherent optical OFDM receiver is demonstrated to receive 28.6-Gb/s data per optical wavelength in single intradyne detection. QPSK modulated sub-carriers are detected using 9.83-GS/s ADCs and DSP implemented on three FPGAs.
Utilizing virtualization technology to combine real-time operating system(RTOS)and off-the-shelf time-sharing general purpose operating system (GPOS)is attracting much more interest recently.Such combination has the potential to provide a large application base,and to guarantee timely deterministic response to real-time applications,yet there is no convincible experimental result about its real-time...
In this paper a real-time scheduling method for steelmaking-continuous casting is proposed to improve the flexibility of scheduling. A directed network model is used to describe steelmaking-continuous casting process considering status of workstations and logistics. First, disturbances including four major kinds are advanced to motivate real-time scheduling in steelmaking-continuous casting process...
System virtualization, which provides good isolation, is now widely used in server consolidation. Meanwhile, one of the hot topics in this field is to extend virtualization for embedded systems. However, current popular virtualization platforms do not support real-time operating systems such as embedded Linux well because the platform is not real-time ware, which will bring low-performance I/O and...
In Recent years embedded world has been undergoing a shift from traditional single-core processors to processors with multiple cores. However, this shift poses a challenge of adapting legacy uniprocessor-oriented real-time operating system (RTOS) to exploit the capability of multi-core processor. In addition, some embedded systems are inevitably going towards the direction of integrating real-time...
Selecting optimal routes to reduce travel time has been an important research area for urban traffic network managements. Various parameters such as route length, average speed and event situations need to be considered in the design of a route guidance system. In this paper, we develop a new navigation system based on the combination of fastest path search algorithm and travel time prediction method...
To improve the viability of hypersonic vehicle in the dynamic environment, the study of real-time trajectory planning has a great value. The high speed of the vehicle determines a higher planning speed. The current level of airborne digital computer determines a very small memory and computing time. All of the limits make the planning more difficult. The viable strategy and the algorithm named improved...
