1. This signal occupies a larger bandwidth than that of normal signal.
2. The spread spectrum signal invariably uses some kind of coding.The spectrum spreading at the transmitter and dispreading at the receiver is obtained with the help of this codeword.
3. The codeword associated with an ss signal is independent of the information carried by the signal.
4. The most important point is that SS signal is psedorandom in nature.
5. This makes it appear like random noise.The normal receiver can not demodulate SS signal.
6. only a specially designed receiver can demodulate it to recover the information.
