Abstract
A method and apparatus determines interpolated intermediated values of a sampled signal. In order to determine interpolated intermediate values of a sampled signal, such as a digital mobile radio signal, the parameters a, b and c of the second-order polynomial y=ax +bx+c are determined starting from three known sample values (x , y ), (x , y ) and (x , y ), so that intermediate values can be calculated using the polynomial. Here it is assumed that the signal is sampled at constant intervals, in particular at intervals normalized to d=1, and the center sample value is assigned to the sampling instant x =0, by which, a calculation can be carried out with low hardware complexity.
