Fast realization of cyclic correlation based symbol rate blind estimation

Abstract:

Some methods of symbol rate blind estimation are introduced. And the basic method based on the cyclic correlation is briefly reviewed. A fast realization method of symbol rate blind estimation based on the cyclic correlation is proposed through theoretic analysis. The method adopts FFT instead of the cyclic frequency scanning. The analysis of the calculation amount shows that the new method is faster than the basic one. Simulation results validate the method. Finally, the defects of the method are analyzed and the solutions are introduced.
