Query: Cooperative Speed Estimation of an RF Jammer in Wireless Vehicular
  Networks   In this paper, we are concerned with the problem of estimating the speed of
an RF jammer that moves towards a group/platoon of moving wireless
communicating nodes. In our system model, the group of nodes receives an
information signal from a master node, that they want to decode, while the
Radio Frequency (RF) jammer desires to disrupt this communication as it
approaches them. For this system model, we propose first a transmission scheme
where the master node remains silent for a time period while it transmits in a
subsequent slot. Second, we develop a joint data and jamming estimation
algorithm that uses Linear Minimum Mean Square Error (LMMSE) estimation. We
develop analytical closed-form expressions that characterize the Mean Square
Error (MSE) of the data and jamming signal estimates. Third, we propose a
cooperative jammer speed estimation algorithm based on the jamming signal
estimates at each node of the network. Our numerical and simulation results for
different system configurations prove the ability of our overall system to
estimate with high accuracy and the RF jamming signals and the speed of the
jammer.
