| Abstract: | In this paper, the basic principles of the DS-SS system are introduced. DS-SS system has ability to combat fading due to multi-path propagation. Rake receiver is designed to minimize the communication errors from muhi-path effects. The design principle of Rake receiver is introduced in the paper, and it shows the simulation results for the Rake receiver of the DS-SS system by MALTAB. |
