Abstract
Fast Fourier transform (FFT) correlation is compared with direct discrete time (DDT) correlation of complex signals in terms of number of operations and memory requirements. The results establish criteria for evaluating which of the two techniques is the more economical in a real time application involving an indefinitely long input data sequence.
