Abstract

The next generation communication system puts forward new requirements in user capacity, communication rate and coverage performance. Non-Terrestrial Network (NTN) communication system, namely satellite network, occupies a very important position. Random Access (RA) process is an important part of communication system, which needs to be completed by random access preambles. Considering the large delay and carrier offset of satellite communication, a sequence design based on coverage sequence is proposed to improve the user capacity. The pruned DFT -Spread filter bank multicarrier (FBMC) is used for signal processing, which can compensate and process the large normalized frequency offset. At the same time, the frame structure is designed to improve the disadvantage that the pruning DFT -Spread FBMC method has no Cyclic Prefix (CP), and a suitable structure is provided for frequency offset compensation.
