Doppler estimation in an OFDM joint radar and communication system

In this paper a processing algorithm that allows for estimating the velocity of multiple reflecting objects with standard OFDM communication signals is discussed. This algorithm does not require any specific coding of the transmit data. The technique can be used in combination with a range estimation algorithm in order to implement active radar sensing functions into a communication system for vehicular applications. Simulation and measurement results which prove the operability of the developed algorithm are presented.
