Abstract |
|
|
| This paper presents a mathematical framework for a family of discrete-time discrete-frequency transforms in terms of
matrix signal algebra. The matrix signal algebra is a mathematics environment composed of a signal space, a finite dimensional linear
operators and special matrices where algebraic methods are used to generate these signal transforms as computational estimators.
The matrix signal algebra contribute to analysis, design and implementation of parallel algorithms in multi-core proccesors. In this
work, an implementation and experimental investigation of the mathematical framework are performed using MATLABr with the
Parallel Computing ToolboxTM. We found that there is advantage to use multi-core processors and a parallel computing environment
to minimize the high execution time. Also, speedup and efficiency increases when the number of logical processor and length of the
signal increase. Moreover, a superlinear speedup is obtained in this experimental investigation. |
