Abstract: A simple lower bound to the capacity of the discrete-time Poisson channelwith average energy $\es$ is derived. The rate ${1-2}\log1+\es$ is shown tobe the generalized mutual information of a modified minimum-distance decoder,when the input follows a gamma distribution of parameter 1-2 and mean $\es$.
