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 r1; determining a second demodulated symbol r2; determining a first parity symbol p1; determining a second parity symbol p2; determining a super-parity symbol q1; and detecting a parity error in the sequence of DQPSK symbols by comparing a combination of the first parity symbol p1 and the second parity symbol p2 against the super-parity symbol q1, wherein a parity between two DQPSK symbols describes a phase difference between the two DQPSK symbols.
