Use of Reinforcement Learning for Interference Avoidance or Efficient Jamming in Wireless Communications
… we study the use of reinforcement learning in an underwater acoustic communications network to adapt its transmission frequencies to avoid interference and potential malicious jammers. To that effect, we implement a reinforcement learning algorithm called contextual bandits. The harsh environment …

Digital communication receiver algorithms and architectures for reduced complexity and high throughput
… near-optimal detection performance for MIMO channels. In order to improve the performance of tree detection, a look-ahead path metric is employed that accounts for the impact of unvisited paths of the tree via an unconstrained linear MMSE estimator. Based on an analysis of the probability of …
