Perception and communication integration method and device, transmitting terminal equipment and receiving terminal equipment

Abstract

The invention provides a perception communication integration method and device, transmitting terminal equipment and receiving terminal equipment, the perception communication integration method is applied to first transmitting terminal equipment, and the method comprises the following steps: aggregating component signals of multiple frequency bands into first radio frequency signals; the first radio frequency signal is an orthogonal frequency division multiplexing (OFDM) signal; and sending the first radio frequency signal. According to the scheme of the invention, by aggregating the component signals of the plurality of frequency bands into the first radio frequency signal, the overall bandwidth of the first radio frequency signal is improved, so that the first radio frequency signal has better distance resolution and better speed resolution, the sensing performance of the first radio frequency signal is improved, and the performance of the first radio frequency signal is improved. As the first radio frequency signal is formed by aggregating the component signals of the multiple frequency bands, the sensing performance requirements of radars of different distances can be met.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for integrating perception and communication, a transmitting end device and a receiving end device. Background technique [0002] When multiple antennas use the same frequency band to transmit different signals, it will inevitably cause aliasing interference between the signals at the receiving end. First of all, TDMA technology cannot be adopted because the transmitter needs to switch quickly, which may cause information loss and have a bad impact on perception performance; secondly, the isolation provided by CDMA technology is not enough to meet the requirements of There is a requirement for multiple high-performance radar sensors in the same frequency band. [0003] In order to enable multiple antennas to work simultaneously and continuously without any performance loss, the transmitted signals must be completely orthogonal. Therefore,...

Problems solved by technology

[0005] The existing technical solutions for transmitting the integrated signal of perception and communication based on the staggered allocation of subcarriers in the same frequency band have the following disadvantages. First, the staggered allocation of frequency spectrum will lead to discontinuity in the frequency domain, which can only ensure the accuracy of the speed. Perception, good ranging performance cannot be guaranteed; secondly, the frequency band used in this technical solution is single, which cannot meet the perception performance requirements of short-range radar and long-range radar at the same time
