Abstract:

Low-altitude small unmanned aerial vehicles (UAV) provide a promising alternative communications solution to boost mobile coverage and connectivity. However, one of the foremost challenges of using UAVs for reliable communications is to predict the channel information between an arbitrary UAV location in the air and a node on the ground, especially in urban environments.

In this talk, I will introduce machine learning based approaches to predict the air to ground channel in urban environments. First, given a probabilistic channel model, neural networks are used to predict channel model parameters based on the received signal strength data. Next, when there is no prior information about the channel model, Gaussian Process is employed to predict the channel information based on measurement. Both methods can keep refining channel prediction and UAV trajectory planning as more measurement data are obtained. Numerical results will be presented to demonstrate the performance of the proposed approaches.
