Abstract :
A measurement experience for the downlink channel of the low earth orbit (LEO) satellites at UHF band was carried out by utilizing a dedicated simulator which could totally simulate an in-orbit LEO satellite. Results including the spectrum of the received signal, the multipath delay over the chip period, the sub-chip multipath delay and the Ricean K-factor were presented for a wide range of propagation surroundings, such as urban, suburban, open environments. The results can be utilized to optimize the design of the LEO mobile satellite systems, especially the Rake-receiving strategy and the dynamic property of the receiver.
