Abstract
In 6G mobile communication technology, accurately perceiving channel state information can significantly improve communication performance, enabling spatial multiplexing and more accurate beamforming. Intelligent holographic radio imaging technology can precisely perceive the electromagnetic space of communication users in complex environments, obtaining interferograms with extremely high spatial resolution and fine spectral resolution. Reconstruction of the K-space can yield information such as the central frequency and azimuth of the incident radio frequency signals. This paper proposes a target detection method based on wavelet packet transform, which can accurately and rapidly detect the center frequency, azimuth, and other information of targets in the reconstructed K-space images obtained from holographic radio imaging. Moreover, hardware acceleration is implemented on FPGA to provide an efficient solution for target detection in channel state information perception.
