Presence detection of multi-phase modulated signal for LEO burst communications

doi:10.7523/j.issn.2095-6134.2013.06.017

Abstract

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.

Key words: LEO satellite, high dynamic, burst communications, multi-phase modulation, signal presence detection
