Abstract
The Internet of things (IoT) technology plays an important role in shipping, vessel tracking, marine engineering and other fields. The space-based Internet of things (S-IoT) is an extension of the IoT in the space field. It is the integration of satellite communications and emerging IoT technology, which will greatly promote the development of the earth integrated network. In this paper, a new non-orthogonal multi-carrier modulation scheme is designed for the machine-to-machine (M2M) communication system to make it applied to space-based networking. This scheme can effectively improve the transmission rate and reduce the sensitivity to frequency offset, so it is suitable for a wide range of data communication environment. The simulation results indicate that the scheme proposed can effectively restrain inter-carrier interference (ICI) caused by non-orthogonal subcarriers, and realize the high speed data transmission rate, which provides a new way for information collection and ship monitoring.
