Webb30 juli 2015 · In the FHSS modulation scheme, data are modulated alongside an orthogonal sequence onto several given frequency channels. In our implementation, the data are omitted (i.e., always equal to “1”), which turns the FHSS modulation scheme into a frequency shift keying (FSK) modulation scheme where the data are given by the … Webb26 feb. 2024 · FHSS is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom or pseudonoise sequence known to both transmitter and receiver. The advantage of this system is that the signal sees a different channel and a different set of interfering signals during each hop.
