What is full form of DSSS?
Direct-Sequencing Spread Spectrum
How can dsss benefits from multipath propagation?
It can't, Prof. Schiller is wrong In contrary DSSS is more vulnerable to multipathing than e.g. FHSS is since it could just ignore its own shadows after jumping.
Spread spectrum techniques fhss and dsss?
"Direct Sequence Spread Spectrum (DSSS)DSSS multiplies the data bits by a very fast pseudo-random bit pattern (PN sequence) that "spreads" the data into a large coded stream that takes the full bandwidth of the channel. DSSS is the basis for CDMA cellphones and 802.11 Wi-Fi wireless transmission. For a technical example of DSSS technology, see cdma.Frequency Hopping Spread Spectrum (FHSS)FHSS continuously changes the center frequency of a conventional carrier several times per second according to a pseudo-random set of channels, while chirp spread spectrum changes the carrier frequency. Because a fixed frequency is not used, illegal monitoring of spread spectrum signals is extremely difficult, if not downright impossible depending on the particular method. FHSS is the transmission technology in Bluetooth. See integrated-business-systems-and-services-inc, wifiand bluetooth."From spread-spectrum
Why signal is spread in dsss?
In Direct Sequence Spread Spectrum (DSSS), the signal is spread to increase its resistance to interference and jamming, enhance security, and allow multiple users to share the same frequency band without significant interference. By spreading the signal over a wider bandwidth using a pseudorandom noise (PN) sequence, DSSS makes it more difficult for unauthorized receivers to detect and decode the transmission. This spreading also improves the system's robustness against multipath fading and enhances the overall reliability of the communication.

What encoding or modulation technology does 802.11 use?
FHSS- Which has been dropped recently DSSS- which is still used by access points to advertise themselves
When was Survey Methodology created?
Survey Methodology was created in 1975.
