Abstract:
An analog frequency inversion scrambler employing an exchange of random number seeds between an originating scrambler (103) and an answering scrambler (107) to create two pseudo-random frequency hopping rolling codes has been disclosed. The rolling code used in one direction of a duplex channel is different than the rolling code in the opposite direction and each code is synchronized by periodic synchronization signals.
