A DTV pilot tone is detected in a noisy environment by computing a power average of Fast Fourier Transform (FFT) output spectra of a received signal, finding a power peak in the averaged outputs, computing an adjustment parameter to center the power peak in a Discrete Fourier Transform bin of the averaged output spectra, applying the adjustment parameter to adjust the received signal, computing a coherent average of FFT output spectra of the adjusted signal, and, testing a power spectrum of the coherent average for the presence of the DTV pilot tone.
