Abstract :
An iterative detection technique for DPSK and its extension to higher level DAPSK modulation schemes is presented. We consider the well-known OFDM transmission technique that requires, in combination with noncoherent detection, no channel state information. By simulation, it is shown that the proposed algorithm leads to a significant performance gain in terms of bit error rate.
