Abstract

This work investigates the design of non-binary protograph low-density parity-check codes for the Poisson channel with m-ary pulse position modulation. The field order over which the code is constructed is matched to the pulse position modulation order yielding a coded modulation scheme. The optimization of the low-density parity-check code structure is performed via protograph density evolution on a surrogate m-ary erasure channel. The surrogate design is illustrated to be not only accurate, but also robust for a range of practical values of channel background noise and various modulation orders. As a result the proposed codes show excellent performances over the Poisson channel with pulse position modulation outperforming competing schemes. As a side-product of the work, finite-length benchmarks on the block error probability are provided, together with a union bound to characterize the code performance in the error floor region.
