As a part of a driver assistance system, vehicle topview system plays an important role in driving safety. The objective of this research is to develop a vision-based top-view system to expand drivers' field of view. Four cameras provide a 360-degree view of the surrounding terrain of the vehicle, and the destination image is composed by these four processed images. In this paper, we divide the procedure...
We model the decoding of Interleaved Chinese Remainder codes as that of finding a short vector in a Z-lattice. Using the LLL algorithm, we obtain an efficient decoding algorithm, correcting errors beyond the unique decoding bound and having nearly linear complexity. The algorithm can fail with a probability dependent on the number of errors, and we give an upper bound for this. Simulation results...
This paper presents a vector control method of AC asynchronous electric motor based on the Digital Signal Processor(DSP) and establishes a mathematical model using double closed-loop decoupled vector control system analysis. The hardware structure, control algorithm and software design flow of the system are described. The key circuit, control circuit and assistant circuit are designed to implement...
We modify the Euclidean algorithm of Feng and Tzeng to decode Reed-Solomon (RS) codes up to the Sudan radius. The basic steps are the virtual extension to an Interleaved RS code and the reformulation of the multi-sequence shift-register problem of varying length to a multi-sequence problem of equal length. We prove the reformulation and analyze the complexity of our new decoding approach. Furthermore,...
The article described constructing, planning and implementing of the electric and electronic virtual experiment system. The system was based on Matlab web server. It was combined by management systems and virtual experiment platform, and adopted Active Server Pages (ASP) to achieve the system's programming. It took the Microsoft Access as the relational database platform for data management experiment,...
