Reinforcement-based data transmission in temporally-correlated fading channels: Partial CSIT scenario
Behrooz Makki, Tommy Svensson, Merouane Debbah
Reinforcement algorithms refer to the schemes where the results of the previous trials and a reward-punishment rule are used for parameter setting in the next steps. In this paper,…
