TLDR
An analog model describing signal amplitude and phase variations on shadowed satellite mobile channels and an M-state Markov chain is applied to represent environment parameter variations show close agreement with measurements.Abstract:
An analog model describing signal amplitude and phase variations on shadowed satellite mobile channels is proposed. A linear combination of log-normal, Rayleigh, and Rice models is used to describe signal variations over an area with constant environment attributes while an M-state Markov chain is applied to represent environment parameter variations. Channel parameters are evaluated from the experimental data and utilized to verify a simulation model. Results, presented in the form of signal waveforms, probability density functions, fade durations, and average bit and block error rates, show close agreement with measurements. >read more

A new simple model for land mobile satellite channels: first- and second-order statistics
TL;DR: A new shadowed Rice (1948) model for land mobile satellite channels, where the amplitude of the line-of-sight is characterized by the Nakagami distribution, provides a similar fit to the experimental data as the well-accepted Loo's (1985) model but with significantly less computational burden.

A statistical theory of mobile-radio reception
TL;DR: In this article, the statistical characteristics of the fields and signals in the reception of radio frequencies by a moving vehicle are deduced from a scattering propagation model, assuming that the field incident on the receiver antenna is composed of randomly phased azimuthal plane waves of arbitrary angle angles.

Measurements and models of a land mobile satellite channel and their applications to MSK signals
TL;DR: Applications of the models to predict performance of a minimum shift keying (MSK) signal at 2400 bits/s show that large margins are required to compensate for the effects of fading and shadowing, and conventional coherent demodulation of a MSK signal may not be feasible due to phase variation caused by fading andshadowing.

The binary regenerative channel
TL;DR: This paper presents a model which provides a reasonable approximation to observed error phenomena which is similar to the model developed by E. N. Gilbert, but several important modifications greatly simplify the estimation of parameters, and make the model correspond more closely to the physical phenomena involved.
