Doppler rate estimation scheme for UFMC based LEO satellite communication system

Doppler‐robust high‐spectrum‐efficiency VCM‐OFDM scheme for low Earth orbit satellites broadband data transmission

“…This work provides hardware feasibility of applying OFDM-based signal in the broadband satellite communication systems. To overcome the dynamic Doppler effects as investigated in [12], a Doppler-based rate adaptive algorithm is proposed in [13] and a Doppler rate estimation scheme with training sequence for LEO satellite communication systems is introduced in [14]. Regarding the slowattenuated side lobes and high out-of-band power emission of conventional OFDM signal, recent research presents a modified waveform, filtered-OFDM in [15,16].…”
