Implementation of Multiple Signal Classification and Triangulation for Localization of Signal Using Universal Software Radio Peripheral

摘要

In this paper, we implement an algorithm that estimates direction of angle (DoA) at each receiver using one transmitter and two receivers and estimates the position of the transmitter using triangulation. In order to implement this algorithm, USRP of NI, which is one of SDR, is used, and GNURadio, which is an optimized program for using SDR, is used as an implementation program. We introduce the equipment setting methods such as phase correction between the equipment and introduce the program to express the position on the GUI. After the implementation, we check the errors of the position of the actual transmitter and the position on the GUI, analyses the performance, discuss the improvement direction and future works.
