Chip rate for fast fhss is equal to
WebWhat is the chip rate for a direct sequence spread spectrum system that has 26 dB of processing gain and a data rate of 90 kbps? Processing Gain = 10 log (Chip Rate / Data … The spread spectrum technique in which the carrier frequency is changed according to the pseudo-random noise or sequence injected is called the frequency hopping spread spectrum (FHSS) technique. The pseudo-random sequence is only available with the transmitter and receiver. The signal transmitted is injected … See more In the direct sequence spread spectrum (DSSS) technique, the signal being transmitted is divided and injected with multiple frequencies within a particular frequency band. The … See more Understanding the differences between FHSS vs. DSSS can help you choose the appropriate spread spectrum technique for any given wireless … See more

See ... WebSpreading sequence in DSSS is represented as being 5 chip long) Notes: 1.- FHSS: The frequency of the carrier has a different value for each dwell time. 2.- DSSS: The …
WebComputer Science. Computer Science questions and answers. 1- OFDM creates several lower-rate (i.e., longer symbol time) subcarriers. Why is that helpful? [Beard, Q. 8.9] 2- … WebThus, for slow FHSS systems, the chip rate is equal to the symbol rate (i., Rc Rs), whereas for fast FHSS systems, the chip rate is equal to the hop rate (i., Rc Rh). In a slow FHSS system with MFSK, the selected M frequencies must be an inte- ger number of symbol rates apart. The spacing is required to maintain orthogonality between the ...
