Abstract

This paper examines the implementation of Wi-Fi devices in signal-processing methods to transmit and receive data reliably in complex wireless networks. It describes radio signal mechanisms at the physical layer for transmitting digital information and decoding it at the other end, accounting for noise, interference, and multipath fading. Such technologies as Orthogonal Frequency Division Multiplexing (OFDM), Multiple-Input Multiple-Output (MIMO), and Channel State Information (CSI) are examined to demonstrate how contemporary Wi-Fi systems become very fast and powerful. It also discusses how these signal-processing techniques support uses like Wi-Fi sensing, security surveillance, and health tracking.
