ABSTRACT:
A method for determining an end of a first period in which signals are communicated in a first direction is provided. The method comprises sampling a signal for a period of time up to at least as long as the longest expected length of the first period to obtain a sampled signal. The sampled signal is integrated to obtain an integrated power curve. A reference line is subtracted from the integrated power curve to obtain a rotated power curve. A peak in the rotated power curve is selected as an end of the first period.
