Abstract

LoRa technology has been widely concerned in LEO satellite communications in recent years, but it still has some problems such as poor anti-Doppler shift capability and low multiple access capacity. Therefore, this paper designed an in-band frequency division multiple access method based on the folded chirp-rate shift keying(FCrSK) modulation with strong immunity to fast time-varying fading. Each user used different initial frequency channels to achieve multiple access, and all users shared the same frequency resources. In addition, this paper analyzed the multi-access interference problem, and proposed an interference cancellation method of FCrSK in-band FDMA based on correction feedback. Compared with LoRa, this method shows better multi-access capacity and stronger Doppler robustness.
