Query: On the Sum-Rate Capacity of Poisson Multiple Access Channel with
  Non-Perfect Photon-Counting Receiver   We first investigate two-user nonasymmetric sum-rate Poisson capacity with
non-perfect photoncounting receiver under certain condition and demonstrate
three possible transmission strategy, including only one active user and both
active users, in sharp contrast to Gaussian multiple access channel (MAC)
channel. The two-user capacity reduction due to photon-counting loss is
characterized compared with that of continuous Poisson channel. We then study
the symmetrical case based on two different methods, demonstrating that the
optimal duty cycle for two users must be the same and unique, and the last
method maybe can extend to multiple users. Furthermore, we analyze the sum-Rate
capacity of Poisson multiple input single output (MISO) MAC. By converting a
non-convex optimization problem with a large number of variables into a
non-convex optimization problem with two variables, we show that the sum-rate
capacity of the Poisson MISO MAC is equivalent to that of SISO under certain
condition.
