Indoor Fingerprinting Localization Based on Fine-grained CSI using Principal Component Analysis
2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)(2021)
摘要
With the development of Wi-Fi technology, the IEEE 802.11n series communication protocol and the subsequent wireless LAN protocols use multiple-input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) technologies. Channel state information (CSI) fingerprint positioning technology based on fine-grained channel state information is widely used in the field of WIFI indoor p...
