Abstract

The present invention relates to the technical field of communication, in particular to a pulse communication method and its device that uses cosine pulse instead of square wave pulse communication, two communication devices designed according to the cosine pulse analog modulation or code modulation signal transmitted on the channel, its A communication circuit for converting square wave pulses into cosine pulses is provided in the shell. Because the present invention has the greatest advantage of narrow occupied frequency band, it also has the advantages of high output power, long transmission distance, no intersymbol interference, significant improvement of signal-to-noise ratio and crosstalk, and the like. In addition, when the sender changes to cosine pulse transmission, the receiver can receive without modification, and the communication quality is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a pulse communication method and a device thereof. Background technique

[0002] As we all know, communication technology is about the generation, processing, exchange, recording, copying, sending, transmission and reception of electrical signals. At this time, electrical signals are the carriers of information, so communication technology is also called the transmission technology of electrical signals. Information is included in all source signals that need to be transmitted, such as text, data, voice, images, and sensors. Different source signals constitute different communication systems, such as telegraph, telephone, radio, fax, television, radar, Remote control, telemetry and artificial intelligence to name a few. The communication system includes signal source, converter, channel, inverse converter and sink, etc., and is usually s...
