Chip rate for fast fhss is equal to
WebA fast FH/MFSK system differs from a slow FH/MFSK system in that there are multiple hops per -ary 𝑀symbol. Hence, each hop of a fast FH/MFSK signal is a chip. We impose the constraint that 𝑠= 𝑁𝑇𝑇𝑐 for fast frequency hopping. For the case of fast frequency hopping, the FHSS signal is given by [7] WebTYPES OF FHSS • Slow hopping: – The symbol rate Rs of MFSK signal is an integer multiple of the hop rate Rh. That is there are several symbols on each frequency hop. Rs=nRh Where n is +ve • Fast hopping – The hop rate is an integer multiple of the symbol rate of MFSK that is in one symbol frequency will hop several times Rh=nRs Where n ...
