Satellite transmissions classically use constant amplitude linear modulation schemes, such as M-state phase shift keying (M-PSK), because of their high robustness to amplifier non-linearities. However, other modulation formats are interesting in a satellite transmission context. For instance, non-linear modulations such as Gaussian minimum shift keying (GMSK) present a higher spectral efficiency and...
We investigate in this paper how to estimate the probability density function (PDF) of a random variable using a rational parametric model for its characteristic function (CF). The choice of the model is motivated by the problem of better modeling the duration of the speech states within a hidden Markov model (HMM). While in the conventional case, the duration of each state is modeled by an exponentially...
