| Abstract: | The basic concept and expressions for a spread spectrum satellite communication system are introduced, and its diagrams for simulation in distortion channel are given. some models for simulation in ACOLADE software are established, including group delay channel and spread spectrum satellite communication system, etc. Some systems, such as QPSK, QPSK DS, QPSK FH, are simulated in group delay channel. Finally, Some useful results are achieved. |
