Following are the difference between slow frequency hopping and fast frequency hopping.
Slow frequency hopping | Fast frequency hopping |
---|---|
In slow frequency hopping, multiple symbols are transmitted in one frequency hop. | In fast frequency hopping, multiple hops are required to transmit one symbol. |
One or more symbols are transmitted over the same carrier frequency. | One symbol is transmitted over multiple carriers in different hops. |
Symbol rate is equal to chip rate. | Hop rate is higher than symbol rate. |
Hop rate is lower than symbol rate. | Hop rate is higher than symbol rate. |
A jammer can detect this signal if carrier frequency in one hop is known. | A jammer can’t detect this signal because one symbol is transmitted using more than one carrier frequencies. |
