Abstract :
A technique to estimate user speed using transmit power control (TPC) commands is presented. We derive a close-form expression of the probability of the derivative of receive signal power exceeding a given threshold as a function of user speed, and show that it has a strong correlation with TPC pattern. The derived equation is used to map between TPC pattern and the corresponding user speed. Simulation results indicate that the proposed estimation technique can achieve accurate speed estimation over a speed range from 1 km/h to 40 km/h.
