This paper proposes a novel phase recovery method for Turbo-coded QPSK systems. The phase estimation is combined with the turbo decoding instead of applying separate synchronisation prior to the Turbo decoder. It is achieved through Maximum Likelihood Estimation (MLE) which employs the extrinsic information obtained from the turbo decoder. Look-up tables are pre-computed to reduce the computation burden. QPSK systems over AWGN channel with unknown phase error are investigated. The phase error… CONTINUE READING
