Signal Distribution Oriented Mean Functions in GPR based Fingerprint Augment

WiFi fingerprinting-based localization is limited by heavy site survey in the offline phase, for which fingerprint augment based on gaussian process regression (GPR) is an effective solution. This paper proposes const-linear (CL) and quadratic polynomial (QP) mean function for GPR based on the cognition of signal distribution in indoor positioning scene. The proposed mean function is designed after comprehensively discussing the complexity of...
