WebThe simulation sequences for fast and slow frequency hopping is the same in number and frequencies of spreading carriers and both used BPSK traditional modulation type.The comparison results based on their power spectral density show that the fast frequency hopping is more resistive to noise the slow one. WebApr 13, 2016 · Frequency hopping spread spectrum is defined in the 2.4 GHz band and operates in around 79 frequencies ranging from 2.402 GHz to 2.480 GHz. Every …
In the frequency hopping technique, the transmitter injects the carrier frequency according to a specific hopping pattern known only to the sender and receiver. The signal transmitted sees several channels and various sets of interfering signals during each frequency hopping event. There is no distinctive frequency … See more According to Shannon’s theorem, when the bandwidth of a signal is wider, the signal is received correctly, even in noisy environments. There is a direct relationship between the channel bandwidth and the … See more A comparison of slow and fast frequency hopping Whenever a signal transmission is facing the threat of jamming or hacking, fast frequency … See more WebNov 19, 2016 · What is fast and slow frequency hopping Wireless Communication Interview Questions And AnswersWireless Communication interview questions,GSM Interview Ques...
