Fingerprint Fusion Location Method Based on Wireless Signal Distribution Characteristic

In the context of rapid development Internet and Things technology, services based on location information have received more attention, people gradually higher expectations for quality experience positioning services. At present, outdoor technology is becoming mature, but different from empty areas, there a highly complex indoor environment with many interference factors, so it difficult to receive effective satellite signals. To realize smooth transition whole-field positioning, necessary study an economical efficient technology. The existing technologies some problems, this paper comprehensively uses resource-rich Wi-Fi signal, Frequency Modulation (FM) signal Digital Terrestrial Multimedia Broadcast (DTMB) as data sources, proposes fingerprint fusion method wireless distribution characteristic. Experiments show that proposed improves localization accuracy by 30% compared alone.
