Abstract
A communications system includes at least two communications units, each communication unit including a transmitter capable of transmitting to the other unit on one or more frequencies, under the control of a mode control unit and wherein acquisition or a locking of frequencies of the two communications units and timing signal recovery is achieved by transmitting signals on a group of predetermined frequencies, the transmission on each frequency being for a predetermined time frame in a sequence which is repeated after n+1 time frames, wherein n is the number of different frequencies to be transmitted by the originating communications unit, and the receiving unit including a receiver operating on one of the predetermined frequencies for n+1 time frames until the receiving unit receives a signal from the originating unit and transmits an acknowledgment signal to the originating unit thus locking the two units on one of the predetermined frequencies such that information, transmission and reception can proceed either in single frequency or in frequency hopping mode.
