Webb• Intermediate (rate) frequency hopping (IFH) B. Slow frequency hopping (SFH) In an SFH spread system the hop rate f H (chip rate) is less than the baseband message bit rate f b. Thus two or more (in several implementations, more than 1000) baseband bits are transmitted at the same frequency before hopping to the next RF frequency. The hop ...
