Method for selecting state of a reconfigurable antenna in a communication system via machine learning

A method of selecting an antenna array state for a multi-element reconfigurable transmitter and/or receiver antenna, comprising the steps of:

• a processor executing a learning algorithm that optimizes unknown signal to noise ratios of possible signal paths between at least one reconfigurable transmitter antenna and at least one reconfigurable receiver antenna over time over different antenna array states of said at least one reconfigurable transmitter antenna and said at least one reconfigurable receiver antenna;
• and
• the processor setting the antenna array configuration for the transmitter and/or a receiver antenna based at least in part on the antenna array states determined by said learning algorithm to lead to optimized signal to noise ratios between said at least one reconfigurable transmitter antenna and said at least one reconfigurable receiver antenna over time,
• wherein executing the learning algorithm includes formulating selection of an antenna array state as a multi-armed bandit problem for learning the unknown signal to noise ratios of said possible signal paths so as to maximize signal to noise ratio between said at least one reconfigurable transmitter antenna and said at least one reconfigurable receiver antenna over time.
