“…Namely, OP is standard measure, often used for controlling the CCI level, in order to meet the QoS and grade of service (GoS) demands. If the environment is interference limited, OP is defined as the probability, that the output SIR of used combiner will fall below defined protection ratio, which depends on applied modulation technique and expected QoS [14,15] …”

In this paper, performance analysis of wireless communication over α − η − μ fading channels has been investigated. First, analysis has been carried out for the case when communication is subjected to the influence of co-channel interference. Closed-form expressions have been derived for the probability density function and cumulative distribution function of the received signal-to-interference ratio. Outage probability has been obtained for this case, in the function of various values of system parameters, and also for the case when selection diversity has been presented at the reception. Further, simultaneous multipath fading and shadowing occurrence has been analyzed, through deriving novel composite Gamma long-time faded α − η − μ fading distribution. First-order statistical parameters have been obtained in closed form, for this novel composite distribution, and capitalizing on them, standard performance measures have been efficiently evaluated, graphically presented and discussed in the function of system parameters.

In this paper, the performance of L-branch selection combining receiver over correlated Weibull fading channels in the presence of correlated Weibull-distributed cochannel interference is analyzed. Closed-form expressions for probability density function and cumulative distribution function of the signal-to-interference ratio at the output of the selection combining receiver present main contribution of this paper. Numerical results are also presented to show the effects of various parameters as the fading severity, correlation and number of branches on outage probability. only one of the diversity branches. Because of that, SC is the least complicated of these three types of linear diversity combining. In general, SC chooses the branch with the highest signal-to-noise ratio (SNR) (or equivalently, with the strongest signal assuming equal noise power among the branches). In fading environments as in cellular communication systems, the level of the thermal noise can be sufficiently low as compared with the level of the cochannel interference (CCI). In that case SC receiver chooses the branch with the highest signal-to-interference ratio (SIR-based selection diversity) [4].In wireless communication systems several statistical models are used to describe fading. The most frequently used models are Rayleigh, Nakagami-m, Rice and Weibull fading channel model. Weibull fading model is a special case of a generalized − fading model [5] and it could be used in land-mobile satellite system and terrestrial radio system due to the fact that it confirms experimentally attained fading channel measurements for both indoor [6] and outdoor [7, 8] environments. However, this model has recently begun to receive some interest. The performance of a class of generalized-selection combining receivers over independent and nonidentical Weibull fading channels has been studied in [9]. Closed-form expressions for the average output SNR, the amount of fading, the outage probability, the switch rate and the average symbol error probability of dual switched and stay combining receivers over independent Weibull fading channels have been extracted in [10,11]. The performance of dual SC receiver over correlated Weibull fading channels has been presented in [12]. In that paper, obtained closed-form expressions for the probability density function (PDF), the cumulative distribution function (CDF), and the moments of the receiver output SNR have been used to consider important performance criteria. In [13], useful analytical expressions for the joint PDF, CDF, moment-generating function and product moments have been derived for both the bivariate and multivariate Weibull distribution with exponential correlation. Moreover, the performance analysis of dual-branch and multibranch SC, EGC and MRC receivers has been studied in that paper. Some important performance criteria of multibranch EGC and MRC receiver operating over nonidentical Weibull fading channels, for both independent and correlative fading, have been derived in [14].The performance analy...
