Polar-Coded Pulse Position Modulation for the Poisson Channel
A polar-coded modulation scheme for deep-space optical communication is
proposed. The photon counting Poisson channel with pulse position modulation
(PPM) is considered. We use the fact that PPM is particularly well suited to be
used with multilevel codes to design a polar-coded modulation scheme for the
system in consideration. The construction of polar codes for the Poisson
channel based on Gaussian approximation is demonstrated to be accurate. The
proposed scheme uses a cyclic redundancy check outer code and a successive
cancellation decoder with list decoding and it is shown that it outperforms the
competing schemes.Comment: 7 pages, 9 figure
