A Method of Moments Estimator for Modulation Index of Continuous Phase Modulation

2019 International Conference on Computing, Networking and Communications (ICNC), 2019
A novel non data-aided estimator based upon the method of moments is proposed for estimating the modulation index of continuous phase modulation (CPM) schemes. Analytical expressions are derived for the asymptotic (large data record N) mean and variance of the estimator using truncated Taylor series.

Higher Order Moments of Error Rates of Digital Modulations

2010 IEEE 71st Vehicular Technology Conference, 2010
Statistics of the conditional error rates of digital modulations over fading channels are considered. The probability density function and the higher order moments of the conditional error rates are obtained using the Prony approximation. For a Ricean distributed channel fading amplitude at the detector input, non-monotonic behavior of the moments of ...

A modulation classification using amplitude moments in OFDM systems

2010 International Symposium On Information Theory & Its Applications, 2010
In adaptive modulation systems, the receiver should identify the modulation employed at the transmitter. This paper presents a new modulation classification method based on amplitude moments and correlation between subcarriers in Orthogonal Frequency Division Multiplexing (OFDM) systems.

Light-induced dipole moment modulation in diarylethenes: a fundamental study

Physical Chemistry Chemical Physics, 2016
The dipole moment of photochromic diarylethenes is determined in solution for both the coloured and uncoloured forms by measuring the capacitance of a capacitor filled with a photochromic solution as a dielectric material.
