Method for piloting from bypass in a network with open wireless channels

A method for piloting from bypass in a network with open wireless channels, comprising:

• 1) Selecting a terminal station as a reference in the open wireless channels, and sending a pilot signal, wherein all or some frequency bands of the open wireless channels are occupied by the pilot signal for transmission;
• the all or some frequency bands of the open wireless channels occupied by the pilot signal are pilot frequency bands, and a proportion of power of the pilot signal to a total power of the pilot frequency bands is 0.1‰-5%;
• 2) Spreading the pilot signal with a spread spectrum code when the pilot signal is transmitted, and then superimposing the pilot signal on a communication signal in the pilot frequency bands in a low power spectrum signal mode similar with noise;
• an influence on a received signal-to-noise ratio of a receiving end signal is lower than an influence on background thermal noise of a receiving end;
• 3) Providing a pilot, a carrier wave synchronization, a clock synchronization, standard timing, and indication information for network construction and mutual communication of multiple types of terminal stations in the open wireless channels by the pilot signal.
