Estimate the states of a vehicle moving along the -axis with respect to constant velocity model. Also estimate the sensor error standard deviation. You can find the measurement vector and the update periods (dt) in the attached MATLAB data file.
This can be done using a Kalman filter, there are some discussion here at <https://dsp.stackexchange.com/questions/8860/kalma...
