Fast frequency hopping
WebApr 11, 2024 · The parameter estimation of multiple frequency-hopping (multiple FH) signals with frequency-switching time is a great challenge under conditions in which the number of signals is unknown. Due to the increasing mobility of devices such as unmanned aerial vehicles (UAVs), speed of parameter estimation is even more demanding. To … WebFeb 2, 2024 · Fast frequency hopping. Since it’s possible to reprogram NCO frequency updates on a time scale of a few microseconds or alternate the multiple NCOs available per signal path in a ping-pong fashion, it is then also possible to receive and transmit frequency-agile signals that follow either repeating or arbitrary sequences.

WebIn fast frequency hopping, time duration between two hops (Th or Tc as shown) <= data bit duration (Tb). This is depicted in the figure-2. The fast frequency hopping provides frequency diversity at symbol level. This will benefit the transmitted signal against fading as well as narrowband jamming. The slow frequency hopping can achieve above ...
