AI Technical Summary

Technical Problem

Existing wireless communication positioning methods based on the JADE-MUSIC algorithm are not effective in noise suppression, resulting in inaccurate positioning.

Method used

By obtaining channel estimates and the signal-to-noise ratio (SNR) of antenna array elements through channel estimation, the arrival time spectrum and arrival direction spectrum are constructed. The observation time spectrum and direction angle are then calculated using SNR weighting to suppress noise effects and improve positioning accuracy.

Benefits of technology

It effectively suppressed the impact of noise on the positioning results, improving positioning accuracy and reliability.
