Abstract
A transmission parameter recognition apparatus and the method thereof are disclosed. The transmission parameter recognition apparatus includes a correlation function processing module, a correlation symbol summing module and an energy interval detection module. The correlation function processing module computes a correction between two adjoining symbols in a sample sequence to generate a correlation function sequence. The correlation symbol summing module accumulates M symbols in the correlation function sequence to generate an energy interval. Since the distribution of the energy interval is related to the guard interval type, therefore, the energy interval detection module detects the distribution of the energy interval to generate a piece of guard interval information.
