Abstract In this paper, calculations of intercarrier interference (ICI) and bit error probability (BEP) of hyperbolic fractional Fourier transform (FRFT) based systems for the satellite internet of things applications, has been considered. Analysis of ICI power and BEP in Rician flat fading channels has been done, mathematically. Simulations approve that the systems based on the hyperbolic FRFT are resistant against carrier frequency offset in high-speed moving conditions. Also, in severely deep fade conditions, the hyperbolic FRFT based systems have an acceptable performance in the achieved bit error probability.

1 Introduction The Internet of Things (IoT) is a creative communication concept which will supply ubiquitous connectivity to everything. It seems that in the near future connection of all objects in all over the world, will be needed. It means having unbreakable communication links in all over the place, is indispensable. The vision for future communication links based on IoT, is to transfer the data between a large number of sensors and a huge number of transceivers. This feature needs such permanent and accessible connections, where all devices can perform their task in the network properly without specific instructions. Utilizing massive wireless networks, broadband cellular services and satellite connection technologies can be such an acceptable solution for connections in future applications [1]. According the scenario of IoT applications, several standardizations and technologies have been developed, recently [2]. The first kind of these technologies are about short-range connections, for instance, Bluetooth, Wi-Fi and Zigbee. This

type of technology, is proposed for some applications such as health care and home automation. The second kind of these technologies is long-range communications. Some systems such as LoRa, Sigfox and LTE machine-type communication (MTC) are in this group, which can utilize in smart agriculture and smart city applications. For wide range industrial applications, such as smart grid, environmental monitoring and geologic disaster forecasting, using low power wide area network (LPWAN) connections is inevitable [3]. The best offer for connections in a wide area which can provide stable and robust links, is utilization of satellite communication links. Satellite networks provide worldwide coverage, which can assure several objects in faraway areas can connect to the same network. Furthermore, constraints of topography such as mountain, valley, forest and sea which degrade the quality of local networks extremely, cannot affec
