Reinforcement Learning-Guided Transmitter Optimization for Short-Reach IM/DD FSO Systems
We propose a reinforcement-learning (RL) guided transmitter optimization framework for short-reach IM/DD free-space optical (FSO) links that jointly tunes probabilistic shaping (PS), geometric shaping (GS), and pre-equalization (Pre-EQ) filter coefficients using the soft actor-critic (SAC) algorithm. The agent adapts t...
