Title: Radio communications apparatus
Inventor: DENT PAUL WILKINSON
IPC: H04K1/00
Filed: 1982-06-11
Granted: 1985-02-28
Abstract: Channel selection in a frequency hopping radio set is controlled by a pseudo-random number generator, the pseudo-random number being used to address an N bit memory (3) which is used to identify each of n available channels from N equipped channels. When a preselected number of the n channels have been identified by the psuedo-random number generator a latch (4) is enabled to store the channel number for selection purposes. Various scrambling methods are employed so that the channels on which one network of radio sets is operating is not readily identifiable from the channels on which another network of radio sets is operating.
