Description

technical field [0001] The invention relates to the technical fields of radio communication and radar, in particular to a unified standard orthogonal wave submultiplexing radio system. Background technique [0002] Since the discovery of electromagnetic waves, people not only have disputes about its nature, but also have different directions in its application, such as radio communication and radar. Radiocommunication technology and radar technology have developed along their respective technological routes since the beginning, and have never really merged into one. [0003] In some environments with strict electromagnetic compatibility requirements and high space utilization requirements, such as the bridge of an aircraft carrier, vehicles in the Internet of Vehicles, etc., the demand for communication and radar integration has become increasingly urgent. First of all, the requirements for communication performance, such as data rate, data volume, anti-interference, etc., ...

Problems solved by technology

Publication number CN101447837A In the single carrier scheme, multi-user communication and multi-target radar detection mainly adopt code division multiple access or spread spectrum technology, such as direct sequence spread spectrum technology, frequency hopping spread spectrum technology and chirp spread spectrum technology, etc. The main disadvantages of the single-carrier solution are the low utilization rate of the spectrum, low performance against frequency dispersion, large amount of calculation, and complex system.

The multi-carrier scheme is mainly developed on the basis of OFDM communication, and the filter bank technology or processing technology based on the modulation symbol domain is used in the communication radar data processing; the main disadvantages of the OFDM scheme The system is complex, the peak-to-average power ratio is high, and the transmission efficiency is not high
