Kalman/Map Filtering-Aided Fast Normalized Cross Correlation-Based Wi-Fi Fingerprinting Location Sensing
A Kalman/map filtering (KMF)-aided fast normalized cross correlation (FNCC)-based Wi-Fi fingerprinting location sensing system is proposed in this paper. Compared with conventional neighbor selection algorithms that calculate localization results with received signal strength (RSS) mean samples, the proposed FNCC algorithm makes use of all the on-line RSS samples and reference point RSS variati...
متن کاملProperties of Channel Interference for Wi-Fi Location Fingerprinting
Localization systems for indoor areas have recently been suggested that make use of existing wireless local area network (WLAN) infrastructure and location fingerprinting approach. However, most existing research work ignores channel interference between wireless infrastructures and this could affect accurate and precise positioning. A better understanding of the properties of channel interfere...
متن کاملWi-Fi Location Fingerprinting Using an Intelligent Checkpoint Sequence
For Wi-Fi positioning location fingerprinting is commonly employed. Fingerprinting, however, is very labour consuming as a database with RSS (Received Signal Strength) scans from all visible access points APs measured on a large number of known reference points has to be established. To overcome this drawback a novel approach is developed which uses a logical sequence of intelligent checkpoints...
متن کاملIndoor Location Sensing with Invariant Wi-Fi Received Signal Strength Fingerprinting
A method of location fingerprinting based on the Wi-Fi received signal strength (RSS) in an indoor environment is presented. The method aims to overcome the RSS instability due to varying channel disturbances in time by introducing the concept of invariant RSS statistics. The invariant RSS statistics represent here the RSS distributions collected at individual calibration locations under minima...
متن کاملFast Normalized Cross-Correlation
Although it is well known that cross correlation can be efficiently implemented in the transform domain, the normalized form of cross correlation preferred for feature matching applications does not have a simple frequency domain expression. Normalized cross correlation has been computed in the spatial domain for this reason. This short paper shows that unnormalized cross correlation can be eff...
