Received-Signal-Strength Threshold Optimization Using Gaussian Processes
2017
IEEE Transactions on Signal Processing
Preserved Fulltext
This paper presents a generic received-signal-strength (RSS) threshold optimization framework for generating informative proximity reports. ...
Among others, we focus on Gaussian process regression (GPR) based RSS models and positioning metric computation. ...
The underlying received signal strength due to path loss is represented by a deterministic, linear log-distance model as follows: m i (p) = A i + 10B i log d i (p) d 0 , (2) where A i is the received signal ...
