Slow fhss

WebbA slow FH/MFSK signal is characterized by having multiple symbols transmitted per hop. Hence, each symbol of a slow FH/MFSK signal is a chip. We impose the constraint that 𝑇 𝑐 = 𝑁𝑇 𝑠 for slow frequency hopping. For … WebbAccording to the frequency at which the RF frequency varies in signal communications, the FHSS technique is classified into either slow frequency hopping or fast frequency …
