Application of Grid computing for designing a class of optimal periodic nonuniform sampling sequences
نویسندگان
چکیده
Designing periodic nonuniform sampling sequences for digital alias free signal processing is a computationally extensive problem where sequential single computer based solutions could easily run for days or even weeks. In order to reduce computation time, the sequential algorithm has been parallelised making it possible to execute parts of the calculations on different nodes of a computational Grid at the same time, reducing the overall runtime of the application. This paper presents and compares two different Grid based implementations representing the two main Grid approaches at the moment. The first solution utilizes a production Grid environment based on GEMLCA and the P-Grade Grid portal, and the second represents a BOINC desktop Grid based solution.

متن کاملOptimal sub-Nyquist nonuniform sampling and reconstruction for multiband signals
We study the problem of optimal sub-Nyquist sampling for perfect reconstruction of multiband signals. The signals are assumed to have a known spectral support that does not tile under translation. Such signals admit perfect reconstruction from periodic nonuniform sampling at rates approaching Landau’s lower bound equal to the measure of . For signals with sparse , this rate can be much smaller ...

This paper proposes a novel structure of model predictive control algorithm for piecewise affine systems as a particular class of hybrid systems. Due to the time consuming and computational complexity of online optimization problem in MPC algorithm, the explicit form of MPC which is called Explicit MPC (EMPC) is applied in order to control of buck converter. Since the EMPC solves the optimizati...
