Description

technical field [0001] The present invention relates to a communication sensing system, in particular to a communication sensing integrated MIMO system based on UWB frequency band. Background technique [0002] As a new type of technology in recent years, the integrated communication and perception system is still in the research stage and has limited application in a small range. The existing communication and perception integrated systems are mainly used in the fields of Internet of Vehicles and indoor positioning, which can provide low-speed communication and two-dimensional positioning between vehicles or between different terminals. However, the existing integrated communication sensing system is still in its infancy, and the communication speed and sensing function are relatively limited. It mainly uses the two-way ranging or the time difference of arrival method to realize the positioning between each terminal, and uses the traditional coding method to achieve The lo...

However, the existing communication-sensing integrated system is still in the initial stage, and the communication speed and sensing function are relatively limited. It mainly uses two-way ranging or time difference of arrival method to realize the positioning between terminals, and uses traditional coding methods to realize The low-speed communication function cannot meet the requirements of the current unmanned driving system for high-precision four-dimensional imaging of the vehicle's surrounding environment and high-speed and low-latency communication between vehicles

On the other hand, for the indoor positioning system, the existing communication-sensing integrated system can realize a relatively single function, only the positioning function, and cannot perform functions such as imaging, speed measurement, and respiratory and heartbeat monitoring, so it cannot meet the requirements of the Internet of Things era. , the requirements of the mutual inductance of the Internet of Everything
