This paper focuses on improving indoor Wi-Fi localization by mitigating the effect of fluctuation received signal strength indication (RSSI). The RSSI data collected at each reference point is first transformed through translation and scaling. BP (Back Propagation) neural network then used to construct ranging model using determine distances between target point. A genetic algorithm (GA) developed optimize initial values weights biases network. For convenience, our proposed denoted as GTBPD....
Due to the strong penetration ability and high transmission rate of ultra-wideband (UWB) signals, UWB technology plays a very significant role in field precise indoor positioning. However, harsh volatile environment leads non-line-of-sight (NLOS) propagation severe attenuation which may generate ranging positioning errors. To mitigate NLOS effect improve accuracy, existing methods use information channel impulse response (CIR) identify signal channels. these identification often require...
Global Navigation Satellite System (GNSS)-Reflectometry (GNSS-R) technology has opened a new window for ocean remote sensing because of its unique advantages, including short revisit period, low observation cost, and high spatial-temporal resolution. In this article, we investigated the potential estimating swell height from delay-Doppler maps (DDMs) data generated by spaceborne GNSS-R. Three observables extracted DDM are introduced estimation, map average (DDMA), leading edge slope (LES)...
Reliable rainfall information is very important for hydro climatology research, industrial and agricultural production, construction, drought flood prediction. As a new remote sensing technology, Global Navigation Satellite System-reflectometry (GNSS-R) can be used to retrieve geophysical parameters due its unique advantages of high spatial temporal resolution, low cost, large coverage, all-weather operation. Existing studies have confirmed that GNSS-R technology detect on the ocean surface,...
Ultra-wideband (UWB) is a very promising indoor wireless positioning technology. However, in the harsh and volatile environment, propagation of UWB signals vulnerable to non-line-of-sight (NLOS) conditions, contaminated range measurements will degrade accuracy for localization. Therefore, it necessary identify LOS/NLOS. Recent studies mainly focus on identification signal conditions by using channel impulse response (CIR) or extracted statistical features. these usually only specific...
