基于5G新空口的感知通信一体化多波束系统
Sensing and communication integrated multibeam system based on 5G new radio
摘要
Abstract
Due to the influence of propagation distance on important signals in multibeam communication channels,there is serial interference and noise,resulting in inconsistent antenna patterns with actual values.Therefore,a perception communication integrated multibeam system based on 5G new radio is designed.The hardware structure of the sensing communication integrated multibeam system is designed by means of 5G new radio multibeam base station,multibeam base station antenna automatic alignment platform,and multibeam acquisition and control platform.On the basis of the system hardware structure,the system software part is designed,multibeam forming method is used to design the 5G new radio multibeam shaping receiving and transmitting subsystem,so as to obtain the antenna pattern.In the subsystem,a hybrid spatiotemporal encoding is implemented using 5G new radio,and the QR decomposition is used to construct the multibeam decomposition channel matrix,so as to eliminate the serial interference in the coding process.According to the channel decomposition results,the channel mapping based method is used to extract the important signals in the multibeam communication channel.The sensing and communication integrated multibeam system based on the 5G new radio is constructed by means of the system hardware and software.The system testing results show that the multibeam forming of the designed system is converging towards the center point,with a maximum antenna direction of 0 dB,which completely coincides with the ideal image and can achieve stable multibeam transmission.关键词
