| Abstract: | This paper mainly deals with the technology of 4 Phases Difference Shift-Keying(4DPSK)and the method of using the SystemView.4DPSK is widely applied in M-PSK systems.It ensures a reliable transfer of information and makes great use of the limited frequency.Besides,it has successfully solved the reverse direction working-problem of the demodulation of the 4 Phases Shift-Keying(4PSK)to better the quality of the communication. |
