spread spectrum does a better job averaging the performance over a frequency band. it is not meant to have better performance than single-carrier approaches, but instead it does an averaging effect. its ideally suited to smooth out 'tone' interference or jamming, average over multi-path fading effects, and handle multi-user environments.

What is The use of multiple frequencies to transmit a signal?
spread-spectrum technology
What is the relation between the bandwidth of a signal before and after it has been encoded using spread spectrum?
there is no basic difference btw the BW. it is the same before & after the SS encoding
Which of the following are criteria that define a transmission method as a spread spectrum technique?
The transmitting signal bandwidth is much wider than would normally be necessary to transmit the information Some influence other than the information being transmitted is used to determine the transmitting bandwidth
What is a full spectrum led light?
a: LEDS emit different color of light or really different frequency that to us means colors. Some LED are manufacture to provide the full spectrum of frequency. so full spectrum
What is the difference between a spectrum analyzer and a network analyzer?
spectrum analyser is single channel and cannot find ratio of phase and magnitude
