Abstract
We introduce in this paper a carrier phase detector suited to transmissions at very low signal to noise ratio. Based on the soft decoding of parity check equations, the synchronization scheme proposed here for a QPSK modulation outperforms a classical decision directed algorithm over a Gaussian channel, and is notably well adapted to satellite applications.
