Abstract
A correlation device is provided that includes an adder for adding an input signal sequence and an auxiliary signal sequence to obtain an addition signal sequence, and a delay element for delaying the addition signal sequence to obtain the auxiliary signal sequence, whereby the delay element has a plurality of coefficient outputs for providing addition signal sequence coefficients. The correlation device comprises further a linking element for the coefficient-wise linking of an addition signal sequence coefficient with a linking coefficient to obtain a correlation result.
