# Chan's Method of TDOA Positioning Simulation and GDOP Calculation MATLAB Simulation of Calculating TDOA using Chan's Method and Calculating GDOP Note: This is one of the course projects of Wireless Sensor Network in UESTC. These codes are used for idea formation and guidance and are definitely not perfect. Therefore please do not just only copy and paste, it could affect your final result of the course. ## Recommended References A Simple and Efficient Estimator for Hyperbolic Location - Y. T. Chan, K.
