Embodiment Construction

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0030] In the field of data transmission, high-frequency electromagnetic waves can carry a large amount of information. The use of high-frequency electromagnetic wave carriers in the present invention can ensure that they can carry a large amount of information; at the same time, spreading the information-carrying signal can greatly improve information transmission. The anti-jamming ability and anti-noise ability, thereby extending the transmission length of information in the cable. figure 1 It is a flowchart of an information transmission method for increasing the transmission length in a cable according to an embodiment of the present invention, such as figure 1 As shown, the information transmission method for increasing the transmission length in a ca...

Abstract

The invention discloses an information transmission method for increasing the transmission length in a cable. The method comprises the following steps: transmitting signals of the transmission information are spread and modulated to high-frequency electromagnetic wave carriers for transmission in the cable; the transmission signals after transmission are demodulated and despreaded to generate a received signal of the transmission information. Based on the information transmission method, the invention also provides an information transmission system for increasing the transmission length in acable. The information transmission method and the system of the invention can carry a large amount of information. The anti-interference ability and anti-noise ability of the information transmissioncan be greatly improved, so that the transmission length of the information in the cable can be prolonged.

Description

Technical field [0001] The invention relates to the technical field of detection methods, in particular to an information transmission method and system for increasing the transmission length in a cable. Background technique [0002] Information transmission is to transmit the transmitted information through electromagnetic wave carrier. However, when electromagnetic waves are transmitted in cables, the transmission distance is limited due to loss and outward radiation. In the prior art, the method of increasing the transmission length is to reduce the frequency of electromagnetic waves, but the amount of information carried by low-frequency electromagnetic waves is relatively small. [0003] Therefore, the present invention provides an information transmission method and system for increasing the transmission length of high-frequency electromagnetic waves in a cable. Summary of the invention [0004] The main purpose of the present invention is to provide an information transmissi...
