Résumé: Analytic expressions for the symbol-error probabilities of M-ary coherent phase shift keying (M-CPSK) detection with an imperfect local carrier reference phase in Nakagami-m fading and additive Gaussian noise are derived. Both the Tikhonov probability density function (PDF) and the uniform PDF of the carrier phase error are considered.We based our analyses on a newly derived expression for the Fourier coefficients of the PDF of the composite phase of the received signal impaired by Nakagami-m fading and additive Gaussian noise. We present a comparison of the results based on the Tikhonov PDF with those based on the uniform PDF in order to show substantial performance differences between these two-phase noise models.
