| Abstract: |
| The performances of a Code-Shift-Keying System(CSKS) is discussed .Two methods for de-spreading the CSKS are given.One method is based on digital-matched-filter(DMF) which has the fastest acquisition speed. The other method is that the DMF is replaced with the cheaper correlator. Finally, the performance analysis of CSKS is made.The Error probability of information code is obtained. |
