WebDirect sequence spread spectrum (DSSS) transmission employs a chipping code to “spread” the transmission over a wider frequency band than it would normally occupy. DSSS is a form of CDMA (see Chapter 4 ). But instead of a pseudorandom binary sequence (PRBS), an 11-bit Barker code is used as the spreading sequence. Web10 de set. de 2015 · One major advantage of FHSS is the fact that it cannot be jammed due to the hopping mechanism it employs. The 802.11 standard switches frequencies every … WebFHSS radios are more susceptible to narrowband noise and interference than DSSS systems, so they will need to retransmit the same packet often. FHSS system will ignore most leaky microwave oven radiation, but with a DSSS system, a interfering signal could overload the receiver and bring the entire link down.. FHSS will still overcome some … high reps or high weight
