Bypass network guiding method in open wireless channel

Abstract

The invention discloses a bypass network guiding method in an open wireless channel. A terminal station is selected from an open wireless channel as a reference; a path of gudie signals are transmitted, the guide signal is sent by occupying all frequency bands or part of frequency bands of an open wireless channel; all frequency bands or part of frequency bands occupied by the guide signal in theopen wireless channel are guide frequency bands; the power of the guide signal accounts for 0.01% o-5% of the total power of the guide frequency band, the guide signal is spread through a spreading code when being sent, the guide signal is superposed on a communication signal in the guide frequency band in a noise-like low-power spectrum signal mode, and the influence on the signal receiving signal-to-noise ratio of a receiving end is lower than that of background thermal noise of the receiving end; the guidance signal provides guidance, carrier and clock synchronization, standard timing and indication information for network construction and mutual communication of multiple types of terminal stations in a channel.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a bypass network guiding method in an open wireless channel. Background technique [0002] Satellite channels are an important category of open wireless channels. In the following technical descriptions, synchronous satellite communication is used as an example of open wireless channels. Other open wireless channel scenarios, such as ground mobile communication networks, radio communication networks, trunking communication network technologies and The application scenarios can be deduced like this. [0003] In the satellite network, there are two basic network forms: star network and mesh network. [0004] In a star network, any two terminal stations need to establish forward link synchronization and reverse link synchronization with the central station first. After the synchronization is completed, the terminal station applies to the central station to join the ...
