"(1) We can gain immunity from various kinds of noise and multipath distortion. (2) It can also be used for hiding and encrypting signals. Only a recipient who knows the spreading code can recover the encoded information. (3) Several users can independently use the same higher bandwidth with very little interference, using code division multiple access (CDMA)."

"The spread spectrum approach to wireless communications is employed today in Wi-Fi and some cellular networks to obtain the following benefits: enhanced reliability - mitigates the impact of wireless interference on a communication channel increased bandwidth - exploits additional wireless spectrum to better utilize and share bandwidth among multiple channels"

Resistance to interception is the second advantage provided by spread-spectrum techniques. Because nonauthorized listeners do not have the key used to spread the original signal, those listeners cannot decode it. Without the right key, the spread-spectrum signal appears as noise or as an interferer. (Scanning methods can break the code, however, if the key is short.) Even better, signal levels can be below the noise floor, because the spreading operation reduces the spectral density.

There are many benefits to spread-spectrum technology. Resistance to interference is the most important advantage. Intentional or unintentional interference and jamming signals are rejected because they do not contain the spread-spectrum key. Only the desired signal, which has the key, will be seen at the receiver when the despreading operation is exercised.

"propagate selection will a better job averaging the actual efficiency over a frequency band. it isn't designed to have got superior functionality when compared with unmarried-carrier strategies, but instead it can an averaging influence. it's ideally worthy smooth out 'shade' hitch or even performing, typical above adjustable-way of life remover side effects, and manage multiple-individual environments.
