Space Coding Schemes for Multiple Human Localization With Fiber-Optic Sensors

摘要: This paper presents a pressure sensing system using fiber-optic sensors for multiple human localizations. The conventional fiber sensor uses complicated hardware such as optical time-domain reflectometer (OTDR) localization, while this aims to develop smart floor with much simpler localization based on binary compressive and low-density parity-check (LDPC) coding. proposed includes LED emitters, plastic fibers, photodetectors, well wireless motes. observation space (or floor) is encoded into set of codes, multidimensional data are generated when targets walk the floor. A Bayesian decoding algorithms developed target those data, given two types logic operations (OR XOR), respectively. experimental results demonstrate location information acquisition capability encoding/decoding scheme high efficiency energy efficiency.
