Abstract
The present disclosure relates to a method for detecting a parity error in a sequence of DQPSK symbols of a digital transmission system, comprising determining a first demodulated symbol r; determining a second demodulated symbol r; determining a first parity symbol p; determining a second parity symbol p; determining a super-parity symbol q; and detecting a parity error in the sequence of DQPSK symbols by comparing a combination of the first parity symbol pand the second parity symbol pagainst the super-parity symbol q, wherein a parity between two DQPSK symbols describes a phase difference between the two DQPSK symbols.
