The invention discloses a single-station full-duplex communication sensing integrated signal design and processing method, and the method comprises the following steps: designing relevant parameters of a sent signal according to sensing performance indexes, such as maximum unambiguous distance, resolution and the like; enabling the communication-sensing integrated transmitter to not only perform low-rate information transmission by using the radar signal subjected to slow time coding modulation, but also transmit a communication signal by using radar echo waiting time, so the spectrum efficiency is improved; enabling the communication receiver to receive and demodulate the radar signal and the communication signal; and enabling the radar receiver to receive signal echoes and sense the distance and the speed of a target through self-interference elimination and radar signal processing. According to the method, the problems of low communication rate, reduced sensing performance, existence of a distance blind area and the like in communication and sensing integration can be solved, and the target detection probability and the system communication efficiency are improved while the sensing precision is ensured by comprehensively utilizing the excellent self-correlation characteristic of the radar signal and the high spectrum efficiency of the communication signal.
Description
technical field [0001] The present invention relates to the field of 6G (sixth generation mobile communication system) radio access network (Radio Access Network, RAN) evolution and the field of communication-sensing integration design, in particular to a single-station full-duplex communication-sensing integrated signal Design and processing methods. Background technique [0002] Wireless perception and wireless communication systems have different design goals and performance indicators, and are usually considered as two independently designed systems, occupying different frequency bands. However, the development of wireless systems and more and more wireless access devices make spectrum resources increasingly scarce. Therefore, how to efficiently use scarce spectrum resources is an important issue for future wireless network development. And, in recent years, with the development of communication technology and communication network, how to use the ubiquitous communicati...
