TRANSCEIVER STATION FOR A FREQUENCY HOPPING INFORMATION TRANSMISSION SYSTEM |
摘要 |
A transmitting-receiving station for transmitting information by frequency hopping comprises a code generator to define the use of a plurality of channels in accordance with a high-speed skip law for a transmitting-receiving station in the stand-by mode, the high-speed skip law consisting in the use of each of the channels during a period of time Tp, while the low-speed skip law governs the change of listening channels used during NxTp, each corresponding to a center channel out of a sequence of N channels of the high-speed skip law. The center channel contains a synchronizing code. The station comprises a memory device to which a write circuit for progressively storing therein the codes produced by the generator and also to which a read circuit is connected to take the codes from the memory as a function of the positions of the transmitting-receiving station. |
