| () |
| Abstract: |
| This paper is concerned with the theoretical analysis of the code synchronization technique of the TDRSS system. It mainly discusses the acquisition method of both fixed length test and sequential detection test. Based on the theoretical analysis and calculated results of the synchronized performance of TDRSS forward and return link,the acquisition performance of sequential detection test is superior to that of fixed length test. |
| Key words: Communication, Direct Sequence Spread Spectrum, Code Synchronization, Fixed Length Test,Sequential Detection Test |
