Time-hopping (TH) is a communications signal technique which can be used to achieve anti-jamming (AJ) or low probability of intercept (LPI). It can also refer to pulse-position modulation, which in its simplest form employs 2k discrete pulses (referring to the unique positions of the pulse within the transmission window) to transmit k bit(s) per pulse.
