Digital signal coding-based method and system for 5th generation (5G) broadband wireless communication

Abstract

The invention provides a digital signal coding-based method and system for 5th generation (5G) broadband wireless communication, which relates to the field of the broadband wireless communication. In the digital signal coding-based method and system for the 5G broadband wireless communication, coding is performed on a high-speed baseband digital signal to form a transmission code, and then, the transmission code is directly sent, transmitted and received, whereas the radio-frequency carrier or the radio-frequency pulse of a traditional wireless communication system, or frequency conversion or modulation / demodulation processing on the signal is not needed. The extension and waveform conversion coding is performed on the high-speed baseband digital signal by the transmitting end of the system disclosed by the invention to form the transmission code, and the transmission code is transmitted through an antenna after being amplified; and at the receiving end of the system, the signal received by the broadband antenna is input to a high-speed sampler or an analog-to-digital converter after being amplified by a low noise amplifier, and then, is input to a baseband for signal processing. The digital signal coding-based system for the 5G broadband wireless communication provided by the invention has the characteristics of simple structure, high transmission rate and low cost, and can be applied to 5G all-digital broadband wireless communication.

Description

technical field [0001] The invention relates to the technical field of broadband wireless communication, in particular, without the need of radio carrier wave and modulation processing of the transmission signal, the high-speed baseband digital signal is directly amplified, transmitted and processed after encoding and waveform conversion processing. A method and system for realizing the fifth generation (5G-5thgeneration) all-digital broadband wireless communication by receiving. Background technique [0002] Information transmission, especially wireless transmission of information, is an important field in modern society. Generally speaking, modern information technology converts analog signal information such as sound and image into digital signal for information processing or storage. For example, logic operations and information storage in computers are all in the form of digital signals. In the optical fiber communication system, the information is also loaded on the ...

Problems solved by technology

The fifth-generation (5G) mobile communication technology is still in the early stage of research and development in the world, and there is no clear international standard for related technologies. The expected wireless transmission rate will be 1 gigabit per second or above

Because the information of computer systems and optical fiber communication systems is stored in the form of digital signals or transmitted in optical fibers, 4G wireless communication still cannot realize the direct interconnection and information transmission between wireless communication and all-digital computer and optical fiber communication.

[0019] Based on the above analysis, it is known that there is no wireless communication system based on digital signal processing of high-speed baseband digital signals. All-digital broadband wireless transmission of information by receiving
