Method of Base Station Positioning for Smart Phone Based on Vector Matching

This paper presents a method of base station positioning for smart phone. This method uses discrete points to represent small areas of the same barrier model, and positions by RSSI feature sampling and vector matching. By avoiding the effect of base station location, signal strength, and transmit model, this method can effectively reduce the error. Experiments in real environment show that the method can recognize two sides of a wall and has a very high accuracy in built-up area.
