Abstract: The present invention discloses a system for indoor localization using distributed wireless channel state information and working method thereof. The system comprises a distributed sensing layer (100) having a plurality of wireless sensing nodes (101A-101N) configured to acquire channel state information from wireless communication packets, a synchronization and aggregation layer (200) comprising an aggregation controller (201) and distributed synchronization engine (203) configured to reconstruct synchronized sensing snapshots using packet sequence association, and a dynamic calibration layer (300) comprising a reference transmitter subsystem (301) and dynamic phase correction engine (303) configured to compensate oscillator drift and phase perturbations. A packet-domain signal processing layer (400) generates covariance matrices and beamforming pseudo-spectra, while an artificial intelligence-assisted localization layer (500) generates indoor localization coordinates corresponding to tracked entities. The invention provides improved localization accuracy, enhanced distributed coherence stability, reduced infrastructure complexity, and real-time indoor localization capability using distributed wireless sensing architecture.
