Signal transmission method and signal transmission system

The invention provides a signal transmission method and a signal transmission system. The signal transmission method comprises the following steps: collecting signals at one side of an obstacle; and performing high-gain transmission on the signals and transmitting the signals to the opposite side of the obstacle, wherein the high gain is a gain that exceeds a preset gain value. According to the signal transmission method provided by the invention, by collecting the signals at one side of an obstacle and performing high-gain transmission on the signals and transmitting the signals to the opposite side of the obstacle, the signals have the capability of penetrating through the obstacle to continue transmission, and the problem that the signals cannot be transmitted or the transmission stability is poor due to the obstruction of the obstacle in the existing signal transmission process is solved, the efficient and stable transmission of the signals after penetrating through the obstacle isachieved, and further th
