| Acquisition and Code Tracing for Spread Spectrum Communication Systems |
|
| () |
| Abstract: |
| In this paper acquisition and code tracing technology for spread spectrum communication systems is analysed. At first,a principle of spread spectrum communication systems is introduced. Methods and performances of acquisition are analysed. Two acquisition and code tracing schematic diagrams are given. Both the theoretical analysis and experimental results indicate that the adopted analysis method and the supposed synchronization scheme are feasible. |
