DEQPSK modulation

    Hello,

    I have implemented a DEQPSK demodulator with complex multiplication.

    Ak = Ik.Ik-1 + Qk.Qk-1
    Bk = Qk.Ik-1 - Ik.Qk-1

    This demodulator good functionning with pi/4 DQPSK

    I would like to demodulate à classic DQPSK with this complex multiplication

    Is it possible and so what is the mapping at the modulator ?

    Thanks
