| Abstract: | Under strong interference environment for the burst-mode direct sequence spread spectrum system,the basic principles of spread spectrum Communication are performance parameters were introduced.The anti-interference ability of the burst-mode direct sequence spread spectrum system with processing gain was discussed. By using ADS software,a design diagram and the observed constellation and modulated spectrum were simulated. From the simulation results,the whole system is disirable. |
