1. A method for frequency based channel scanning comprising:

  • placing a demodulator in a power scanning mode;

    scanning a frequency spectrum to obtain power samples at a plurality of frequencies;

    comparing the power samples to a threshold power to detect a channel, wherein the detected channel comprises a flat area, a left point of inflection, and a right point of inflection;

    performing channel extraction once the channel is detected; and

    obtaining a coarse estimate of the channel parameters associated with the detected channel, wherein obtaining the coarse estimate comprises measuring power at three separate frequencies for the left point of inflection for the channel.
