What does the term 'hopset' refer to in frequency hopping?

The term 'hopset' specifically refers to a programmed set of frequencies used for hopping in frequency-hopping spread spectrum communication systems. This set contains the specific frequencies that a transmitter and receiver will use as they switch between different frequencies during transmission. The design of a hopset is crucial as it determines the pattern and sequence of frequencies used, which enhances security and reduces the likelihood of interference or eavesdropping.

In frequency hopping, the transmitter rapidly changes its frequency according to the patterns defined in the hopset, allowing the signal to resist jamming and detection. It is essential for ensuring that the communication remains secure and robust in various operating environments.
