通过仿真概率密度曲线逼近理论曲线的程度和程序运行效率两方面对生成Nakagami-m分布随机变量的几种典型方法———Brute force法、正弦求和法、逆变换法性能进行研究和比较.结果表明,无论是对理论曲线的逼近程度还是运行效率,逆变换法都是三种方法中最优的.Nakagami-m衰落信道仿真时应优先考虑逆变换法.
Several typical methods to generate Nakagami-m distributed random variables, such as Brute force method, sinusoidal summation method and inverse transform method, are studied and compared by simulating the degree to which the probability density curve approaches the theoretical curve and the program running efficiency. The results show that the inverse transform method is the best of the three methods, no matter the approximation of the theoretical curve or the operation efficiency, and the inverse transform method should be given priority in the simulation of Nakagami-m fading channel.
