A self-organization satellite communication system based on single-frequency

Satellite communication network structure is generally divided into star network, mesh network and hybrid network. Generally, a main station will be set up in the network, through which the control, detection, management and maintenance of the entire network can be implemented. One of the drawbacks of the network containing main station is its strong dependence, once the main station is malfunctioned or destroyed, the whole network will paralyze. In the network management structure, the network corresponding to the network with a main station is generally defined as self-organization network. This paper proposes a self-organization method based on single-frequency TDMA for small satellite communication network, which can transmit multiple type of business and contains a small number of sites. As there is no main station, the construction period is shorter and the cost is lower. Each site takes up free time slot by sending/receiving tests and initiates communication, thus the whole process is flexible and easy.
