Abstract

The invention relates to a satellite communication method, a satellite and a satellite system, and the satellite communication method comprises the steps: taking a time slice as a period, employing a first spot beam to cover wave positions in a first wave position group one by one in a time-sharing manner, and carrying out the OFDM communication with satellite terminals in the wave positions; the method for covering the wave positions in the first wave position group one by one by using the first spot beam in a time-sharing manner and performing OFDM communication with the satellite terminals in the wave positions comprises the following steps: performing OFDM communication with the satellite terminals in the first wave positions by using the first spot beam within the wave position service time of the first wave positions; and performing OFDM communication with a satellite terminal in a second beam position by using the first spot beam in the beam position service time of the second beam position.

Description

technical field [0001] The present application belongs to the field of satellite communication, and in particular relates to a satellite communication method, a satellite and a satellite system. Background technique [0002] At present, the existing multi-spot beam broadband satellite systems mostly use a fixed way to allocate resources such as on-board power and bandwidth. This resource allocation method is not flexible enough, which can easily result in limited satellite performance. The satellite capacity is reduced, and the work efficiency and competitiveness of the satellite system are reduced. [0003] The existing beam hopping scheme cannot support OFDM waveform modulation technology, and based on DVB series standards, it cannot be compatible with OFDM waveform. At the same time, the first-use scheme is generally suitable for single-satellite satellite communication systems, but cannot be applied to constellation communication systems. The compatibility between the...
