Abstract
The present disclosure provides an RSS (Received Signal Strength) signal correction method for performing location measurement by utilizing information among a plurality of nodes, and the RSS signal correction method estimates a variable of an RSS signal model based on at least one of location information of a fixed node, location information of an unknown node and measurement noise information of the unknown node.

A Received Signal Srength (RSS) signal correction method for performing location measurement by utilizing information among a plurality of nodes, the RSS signal correction method comprising:
- estimating a variable of an RSS signal model based on at least one of location information of a fixed node, location information of an unknown node and measurement noise information of the unknown node:
- deriving the RSS signal model based on at least one of the location information of the fixed node, the location information of the unknown node and the measurement noise information of the unknown node;
- vectorizing the derived RSS signal model;
- and
- calculating an RSS signal model parameter by deriving a Partial EIV (Errors-in-Variables) model from the vectorized RSS signal model,
- wherein the parameter includes a path loss at a reference distance and a path loss exponent that is a ratio of an RSS silo reduced as a distance between nodes increases.
