Abstract: According to a method for localizing a transmitter inside a building, a transmitter emits rays which undergo multiple reflections with the walls, ceilings and floors of the building. Each of K receivers receives rays from the transmitter, and the receivers estimates the AOA (Angle of arrival), TOA (Time of Arrival) and power of each ray. At least one of the receivers uses a known blueprint of the building and material characteristics of the walls to localize the transmitter to a higher degree of accuracy by applying a backward ray tracing algorithm.

Abstract translation: 根据用于将建筑物内的发射器定位的方法，发射器发射与建筑物的墙壁，天花板和地板进行多次反射的射线。 每个K个接收器接收来自发射机的光线，并且接收机估计AOA（到达角度），TOA（到达时间）和每个射线的功率。 至少一个接收器使用建筑物的已知蓝图和墙壁的材料特性，通过应用反向光线跟踪算法来将发射器定位成更高的准确度。
