Problems solved by technology
[0002] The ground wave signal is transmitted in the form of medium and long waves. During the transmission process, the ground wave signal is easily affected by complex environmental noise, resulting in signal distortion.
Related technologies generally manually select a target frequency from each transmission frequency for ground wave signal transmission, but the process of target frequency selection takes a long time and the selected target frequency has poor ground wave signal transmission effect in complex environments

Description
technical field [0001] The present application relates to the field of communication technologies, and in particular, to a ground wave signal transmission device and a transmission system. Background technique [0002] The ground wave signal is transmitted in the form of medium and long waves. During the transmission process of the ground wave signal, it is easily affected by complex environmental noise, resulting in the signal being easily distorted. In the related art, a target frequency is generally selected from each transmission frequency for ground wave signal transmission manually, but the target frequency selection process takes a long time and the selected target frequency has poor ground wave signal transmission effect in a complex environment. SUMMARY OF THE INVENTION [0003] The embodiment of the present application discloses a ground wave signal transmission device and a transmission system, which can select a transmission frequency with the best ground wave ...
