Abstract :
We address the problem of adaptive sampling and estimation of non-wide sense stationary vehicle to vehicle (V2V) wireless channels. In the proposed solution the transmitter utilizes the current channel statistics to dynamically change the number of pilot symbols in every radio frame. The receiver first decodes the location of the pilot symbols and then selects channel estimation filter weights to match the current channel statistics.
