Problems solved by technology

[0004] However, in the prior art, since the sending end needs to send 224 carrier signals and 224 module switch control signals to the RF power module of the receiving end through the connecting cable between the sending end and the receiving end, the sending end and the receiving end A large number of connecting cables are required between them, and a large amount of wiring resources are required, and due to the large amount of wiring, each carrier signal and each module switch control signal are signals of the same frequency, so that there will be interference of the same frequency between the two types of signals

Abstract

The invention provides a signal transmission method, a signal transmission device and a signal receiving device. The method comprises the steps of carrying out parallel-to-serial conversion processing on m parallel module switching control signals according to clock signals of which carrier frequency is multiplied by p and carrier signals with equal duty cycles, thereby obtaining n serial module switching control signals; carrying out drive processing on the clock signals of which carrier frequency is multiplied by p and the carrier signals with the equal duty cycles, thereby generating n clock signals of which carrier frequency is multiplied by p and n carrier signals with the equal duty cycles; and sending the n serial module switching control signals, the n clock signals of which carrier frequency is multiplied by p and the n carrier signals with the equal duty cycles to a signal receiving device, wherein the m is equal to n*p, the m is greater than 1 and is smaller than or equal to 224 and the m is a positive integer, the n is greater than 1 and is smaller than or equal to 28 and the n is the positive integer, and the p is the positive integer. A great number of wiring resources are reduced, and the same frequency interference between the carrier signals and the module switching control signals is reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a signal transmission method, a signal sending device and a signal receiving device. Background technique [0002] Broadcasting transmitters mainly use high-power medium-wave transmitters for local coverage of medium-wave broadcasting in a large area (such as within the province). Currently, high-power medium-wave transmitters can only achieve single-frequency broadcasting due to the complexity of technical implementation. , even if the broadcasting frequency is replaced, it will require expensive renovation funds. In the operation and maintenance process of the transmitting station, in order to ensure the uninterrupted broadcasting, it is necessary to equip a spare transmitter. The way of broadcasting needs to install a spare machine for each transmitter, and the engineering investment and equipment maintenance costs are very huge. [0003] In the prior art, a multi-frequency...
