New computationally-efficient correlation techniques are proposed for time delay estimation of radio-frequency (complex) signals and their performance analyzed by computer simulations. From the comparison with the direct multiply-and-accumulate method, complex hybrid sign (CHS) and complex polarity coincidence (CPC) correlators reveal interesting trade-offs between estimation accuracy and computational complexity. 'Full' and 'reduced' structures of the proposed estimators (and of the direct correlator) have been taken into account.
