Abstract

A bandwidth efficient coding scheme for iterative receivers is investigated. Blockwise noncoherent M-APSK channels are considered. The scheme proposes a new approach for a iterative receiver based on factor graphs. The approach considers the use of differential encoding and non-binary modulations. A comparison of the performance scheme for LDPC codes with short lengths is described.
