Chip rate for fast fhss is equal to
WebDSSS and FHSS are the two techniques most in use today. Direct-Sequence Spread Spectrum (DSSS) With the DSSS technique, the PRN is applied directly to data entering the carrier modulator. The modulator, therefore, sees a much larger bit rate, which corresponds to the chip rate of the PRN sequence. WebSchool of Computing and Information University of Pittsburgh

WebChip (CDMA) In digital communications, a chip is a pulse of a direct-sequence spread spectrum (DSSS) code, such as a pseudo-random noise (PN) code sequence used in direct-sequence code-division multiple access (CDMA) channel access techniques. In a binary direct-sequence system, each chip is typically a rectangular pulse of +1 or −1 amplitude ... WebSep 11, 2024 · FHSS Technology Futaba introduced FHSS (Frequency Hopping Spread Spectrum) systems in 2010, to offer modelers a less expensive way to enjoy 2.4GHz dependability. Other advantages include extremely low latency, exceptionally fast frame rates, transmitters with no external antennas and low-cost receivers with Easy Link …
WebFHSS is less reliable. DSSS is more reliable. The analog to digital conversion in FHSS takes less time. The time taken to convert an analog signal to digital is higher. At a lower transmission rate, FHSS is cheaper. The implementation of DSSS at radio frequencies with a high transmission rate is cheaper. FHSS is not dependent on the distance of ... http://www.sis.pitt.edu/prashk/inf1072/Fall16/lec8.pdf

For a data rate R, the duration of a bit T= 1=R, so the duration of a signal element is T s= log 2 MT. If T c T s, the system is referred to as a slow FHSS; otherwise, it is a fast FHSS. In FHSS, the bandwidth of a hop is W d= MF d, where Mis the number of di erent signal elements. The total irony literary device example
