Wireless geolocation techniques make use of measurements of signal strength, time-of-arrival (TOA), angle-of-arrival (AOA), or their combinations. With different degrees of reliability of the measurement data, how to efficiently coordinate all the available information is crucial. The factor graph together with the sum-product algorithm, which makes the optimum use of the data statistics, is a perfect candidate for such a task. So far, most existing position location techniques focus on… CONTINUE READING
