摘要
Abstract
The Multiple Frequency and Time⁃Division Multiple Access ( MF⁃TDMA) is a multiple access technology based on the combination of frequency⁃domain and time⁃domain. This technology has some special advantages in flexible networking and integrated service transmission in satellite communications, so it is suitable for different satellite communications. Aiming at the MF⁃TDMA signal used widely in current satellite communication domain, this paper analyzes the time⁃frequency characteristics and the carrier features of signal. An integrated MF⁃TDMA signal detection method is put forward based on cumulative spectrum calculation, search in frequency domain and detection of energy window in time domain. The multicarrier detection and carrier features of MF-TDMA signal are ana⁃lyzed. The actual data proves the validity and feasibility of this method.关键词
