| Abstract: | The conception of cyclostationary signals is introduced first Guitin; analysis of the cyclostationary properties of direct spread spectrum signals in the DS -CDMA systems is then discussed in detail. The simulations shows that it is practical to take advantage of the cyclostationary properties between signals and interference added with noise for signal detection or interference rejection. |

| Keywords: | cyclostationary direct spread spectrum signal signal detection interference rejection |
