Abstract

Some embodiments relate to an encoder (830) comprising a differential encoder (810) operable to provide a differentially encoded signal (811) based on an input signal (105) and a differential encoding rule; and an LDPC encoder (806) operable to provide an LDPC encoded signal (807) based on the differentially encoded signal (811) and based on an LDPC encoding rule corresponding to anM'S×N'Sparity check matrix (H') comprising a plurality ofS×Spermutation sub-matrices with an even number of non-zero entries in each row of anS×Ssub-matrix. Further embodiments relate to a decoder (840) comprising an LDPC decoder (822) operable to provide an output signal (823) based on an input signal (821) and based on an LDPC decoding rule corresponding to anM'S×N'Sparity check matrix (H') comprising a plurality ofS×Spermutation sub-matrices with an even number of non-zero entries in each row of anS×Ssub-matrix; and a differential decoder (818) operable to provide a decoded signal (819) based on the output signal (823) from the LDPC decoder (822) and a differential decoding rule.
