“…In the following, we describe the structure of the detector based on the work in [12], [21], followed by a discussion on the decoder. 1) Detection: The role of the detector is to provide an estimate of the symbol-wise probability P(a i |r), which is divided element-wise by the priors P(a i ) and normalized, to obtain the extrinsic information L E,det i that is forwarded to the decoder.…”

“…In contrast to many existing works, we make use of non-binary LDPC codes over finite fields, owing to their excellent performance over the AWGN channel for short blocks [22], [23], [24], [25]. Compared to [21], we directly perform the code design of the concatenated scheme for the non-coherent Wiener phase noise channel and also present useful finite-length benchmarks for this channel. Furthermore, we introduce a refinement step in the code design process, aiming at lowering the error-floor.…”

This work considers the design of short non-binary low-density parity-check (LDPC) codes over finite fields of order m, for channels with phase noise. In particular, m-ary differential phase-shift keying (DPSK) modulated code symbols are transmitted over an additive white Gaussian noise (AWGN) channel with Wiener phase noise. At the receiver side, noncoherent detection takes place, with the help of a multi-symbol detection algorithm, followed by a non-binary decoding step. Both the detector and decoder operate on a joint factor graph. As a benchmark, finite length bounds and information rate expressions are computed and compared with the codeword error rate (CER) performance, as well as the iterative threshold of the obtained codes. As a result, performance within 1.2 dB from finite-length bounds is obtained, down to a CER of 10 −3 .
