Measurement Based Visualization Method of Radio Wave Environment Using a Mode Seeking Algorithm

Abstract

In this paper, we propose an algorithm to visualize radio wave environment based on the measured Received Signal Strength Indication(RSSI) and 3D geographic information. We estimate the source position using the circumcenter of the triangle and visualize the radio wave environment using the empirical propagation models. A mode seeking algorithm(mean-shift clustering) is used to seek the peak points and the center of gravity is utilized to reduce the estimation errors. Our approach finds its applications in the radio wave monitoring systems for the efficient utilization of radio resources.
