Abstract
In this memo, the probability density functions (pdfs) for the phase and the envelope of an amplitude-modulated (AM) signal, where the modulation is modeled as a Gaussian random process, in the presence of narrow-band Gaussian noise are calculated. An exact, closed-form expression is obtained for the phase pdf, while approximate results, accurate for small and large carrier-to-noise ratios (CNRs), are derived for the envelope pdf.
