“…The ADF of the instantaneous channel capacity denotes the average duration of time over which the instantaneous channel capacity is below a given level [20,21]. In the literature, the analysis of the LCR and ADF has mostly been carried out for the received signal envelope, which provides useful information regarding the statistics of burst errors occurring in fading channels [22]. However, in [23], the channel capacity for systems employing multiple antennas has been proposed as a more pragmatic performance merit than the received signal envelope.…”

This article deals with the derivation and analysis of the statistical properties of the instantaneous channel capacity a of N*Nakagami-m channels, which has been recently introduced as a suitable stochastic model for multihop fading channels. We have derived exact analytical expressions for the probability density function (PDF), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades (ADF) of the instantaneous channel capacity of N*Nakagami-m channels. For large number of hops, we have studied the first-order statistics of the instantaneous channel capacity by assuming that the fading amplitude of the channel can approximately be modeled as a lognormal process. Furthermore, an accurate closed-form approximation has been derived for the LCR of the instantaneous channel capacity. The results are studied for different values of the number of hops as well as for different values of the Nakagami parameters, controlling the severity of fading in different links of the multihop communication system. The results show that an increase in the number of hops or the severity of fading decreases the mean channel capacity, while the ADF of the instantaneous channel capacity increases. Moreover, an increase in the severity of fading or the number of hops decreases the LCR of the instantaneous channel capacity of N*Nakagami-m channels at higher levels. The converse statement is true for lower levels. The presented results provide an insight into the influence of the number of hops and the severity of fading on the instantaneous channel capacity, and hence they are very useful for the design and performance analysis of multihop communication systems.

In this paper, an analytical model for a land mobile satellite channel is introduced that takes into consideration the Generalized Rice model for characterizing the small scale (fast) fading. The proposed model is enriched by the property of non-homogeneous scattering allowing higher flexibility and a more comprehensive description of the channel. In addition, a lognormal process affects the line of sight component, in order to characterize the large scale (slow) fading due to the shadowing effect caused by physical obstacles such as trees and small buildings. The main statistical properties of the model are investigated. Exact solutions for the power spectral density, the probability density function of the envelope and phase, and the cumulative distribution function of the envelope are derived. Approximate solutions for the level crossing rate and the average duration of fades are obtained. The validation of the model is confirmed by simulation and demonstrated by providing the best fit to certain measurement data corresponding to conditions of light and heavy shadowing. As a conclusion, the extended Loo model is applicable in realistic land mobile satellite channels subjected to various conditions and can be preferable because of its outperformance.

“…These quantities are also called second order statistics because they take into consideration the time dimension. In addition to their importance in providing statistical information on the error bursts [18], [19], these quantities are also useful for computing transition probabilities in Markov modeling of fading channels [20], and in velocity estimation of mobile units [21]. Using the traditional PDF-based approach, an analytical expression for the LCR of the process R(t), denoted by N R (r), can be obtained by solving the following integral [10] …”

Abstract-In this paper, study of the second order statistics of the Nakagami-Hoyt fading channel model (Nakagami-q model) is considered. Expressions for the level crossing rate (LCR) as well as the average duration of fades (ADF) are derived. It is shown that the obtained analytical quantities best fit the corresponding measurement data for an equivalent mobile satellite channel in the case of an environment with heavy shadowing. This leads to the conclusion that the Nakagami-q model is applicable to realistic mobile communication channels. A simple and efficient deterministic simulation model based on the Rice's sum of sinusoids, which enables the emulation of the fading envelope of the Nakagami-q model with the desired statistics, is also described. A very good agreement is obtained between the simulated, analytical, and experimental statistics.
