Python implementation of the simulation for paper "Computationally Efficient and Location Robust TDOA Positioning Estimator in MPR for IoT Device"
By Chengyu Li and Y. Sun, College of Computer Science, Sichuan University
A computationally efficient and location robust estimator for TDOA localization in MPR, which is designed for IoT device. The solution performs similarly to the GTRS solution [1] but requires less computational load.
