| Abstract: | A new signal presence detection method of MPSK signal, suitable for LEO burst communications, is proposed. The new method uses E(I2+Q2)2] as the detection quantity, and it has simple digital structure and is convenient for onboard implementation. The theoretical derivation, simulation validation, and analysis for this method are presented. In the specific applications, the performances of detection probability and false-alarm probability are simulated. |
