Abstract :
An analysis of adjacent and nonadjacent double differential M -ary PSK (M-ary D2PSK) on the Rician channel is presented. The probability density function of the first-order phase error (FOPE) and the probability density functions of the second-order phase error (SOPE) for both adjacent and nonadjacent D2PSK on a fading channel have been derived. Asymptotic approximations for these PDFs are proposed in the case of channels with weak fading (including the AWGN channel) and high signal-to-noise ratio. For nonadjacent D2PSK with independent FOPEs a simplified PDF of SOPE has been obtained. The derived PDFs allow one to calculate the error performance of D2PSK, as well as DPSK, on the Rician channel, including the AWGN channel and the Rayleigh channel, and to verify some results obtained in earlier publications for D2PSK on the AWGN channel
