Abstract
New reliable and accurate capacity bounds for Poisson channel modeled optical communication system are derived under peak-power and average-power constraints. The bounds are based on two entropy inequalities of Poisson random variables. Simulation results show that the proposed bounds are much tighter than previous ones, especially at lower signal-to-noise (SNR) region, where most wireless optical links typically operate.
