<p>A guard interval correlator suitable for the calculation of a guard interval correlation and a correlation producing method therefore are disclosed. A first delay delays an input value by the length of a guard interval while a subtractor subtracts a correlation delayed by one clock from a delayed output. An adder adds the input value and the delayed output. Further, a second delay delays the resulting sum by one clock to thereby output a correlation. This is successful to prevent the circuitry from being scaled up without degrading the accuracy of the correlation. <IMAGE></p> |
