Cooperative communication using multiple relays improves quality of service (QoS) parameters of a communication system. To verify this improvement, accurate analysis must be done considering the various fading channels and probability density function (PDF) or cumulative distribution function (CDF) of signal-to-noise ratio (SNR) in relays and destination. In this paper, using the moment-generating function (MGF) method and considering Nakagami-m fading channel, the outage probability and effective capacity are analyzed. Obtaining the closed-form expression of outage probability and effective capacity in Nakagami-m fading channel includes complex mathematical calculations; thus, the Rayleigh fading channel is assumed to be a special case of Nakagami-m distribution to achieve simpler mathematical equations. Simulation results verify the mathematical analysis in terms of effective capacity and outage probability.

在协作通信系统中使用中上和瑞利衰落信道上的矩生成函数进行有效容量和中断分析

使用多个中继的协作通信可提高通信系统的服务质量（QoS）参数。为了验证这一改进，必须考虑中继器和目的地中的各种衰落信道和概率密度函数（PDF）或信噪比（SNR）的累积分布函数（CDF），进行准确的分析。在本文中，使用的时刻生成函数（MGF）方法并考虑Nakagami-米衰落信道，中断概率，有效的容量进行了分析。获得中断概率和有效容量的封闭形式的表达式中Nakagami-米衰落信道包括复杂的数学计算; 因此，在瑞利衰落信道被假定为的Nakagami-一个特例米分布以实现更简单的数学方程式。仿真结果验证了有效容量和中断概率方面的数学分析。
