Webb5 dec. 2024 · We have a slow-hopped signal in the FH system if the hopping is performed at the symbol rate. As a result, with slow-frequency hopping, the MFSK signal's symbol rate Rs is an integer multiple of the hop rate Rh, implying that various symbols are transmitted per each frequency hop. Frequency hopping example: Webb- Slow FHSS = multiple signal elements per hop - Fast FHSS = multiple hops per signal element What is Code Division Multiple Access (CDMA)?
