Capacity of the L/sub p/ norm-constrained Poisson channel
Michael R. Frey · IEEE Transactions on Information Theory · 1992
The capacity of the Poisson channel is derived with a specified constraint imposed on the L/sub p/ norm // chi t///sub p/ of the encoder intensity chi . Formulae are given for the capacity which establish previously known results for p=1, p=2, and p= infinity to be part of a system of capacity problems with common form and solution. These formulae apply with or without causal feedback and whether or not the encoder intensity is OOK (on/off keying)-constrained.>
