<p>A method of acquiring frequency bursts in a PCN broadcast control channel, including the steps of: i) sampling PCN r.f. signals for successive blocks of time of duration of half the duration of a frequency burst; ii) determining the first block to have a spectrum level to exceed a threshold value, iii) comparing the spectrum levels of said first block and an adjacent block during successive occurrences of the frequency burst; and iv) adjusting the timing of the two blocks until the spectrum levels of the two blocks are substantially equal. <IMAGE></p> |
