  • Method and apparatus for television band pilot sensing
    Patent number: 9143774
    Abstract: A DTV pilot sensor generates DTV pilot tone detection decisions associated with monitored television band channels without knowledge or estimation of a noise level of the monitored channel.
    Type: Grant

  • Method and apparatus for detecting the presence of a DTV pilot tone in a high noise environment
    Patent number: 8949061
    Abstract: 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.

  • Method and apparatus for dynamically generating multiple level decision thresholds of an M-ary coded signal
    Patent number: 6317062
    Abstract: A method and apparatus for dynamically generating multiple level decision thresholds of an M-ary demodulated signal for decoding the signal. The threshold values are obtained by obtaining the maximum and minimum peak values of the demodulated M-ary signal, averaging these peak values and subsequently processing these averaged values to establish the threshold for the particular M-ary signal. Infinite impulse response filters may be advantageously used in the averaging process and these filters may be preloaded with maximum and minimum peak values such that decision threshold levels may be generated immediately after receiving the M-ary demodulated signal.
