Joint Position and Velocity Estimation for Cooperative Networks using Full-Duplex Radios

In mobile scenarios, the position and velocity of each node in the wireless network are of importance for many applications. Using the full-duplex communication technology, we propose a joint position and velocity estimation scheme for cooperative networks. We first derive the closed-form expression of the Fisher information matrix, which characterizes the accuracy of the joint position and velocity estimation. Then, we propose a mutual interference cancellation scheme on the two-dimensional channel impulse response for channel parameter estimation, as well as a joint position and velocity estimation algorithm for cooperative networks. The simulation results illustrate that the performance of the proposed algorithm is close to the lower bound.
