一种K分布随机数产生方法

Abraham（2002）从海底散射的物理现象出发。提出并证明了有限个幅度服从指数分布，相位服从均匀分布的复随机变量之和的模服从K分布．本文以Abraham的上述理论为基础构造了一种K分布随机数产生方法．该方法以一组相互独立。在区间0，1]服从均匀分布随机数为基础，经过一系列运算，即可产生服从K分布的随机数．还对该方法进行了仿真分析，结果表明该方法可以有效地产生K分布随机数，而且比较简单，易于实现。

Generator of K-Distributed Random Number

Abraham (2002) presented and proved that the envelope of the sum of finite complex random variables, whose amplitude obeys exponential distribution and phase obeys uniform distribution, is K distributed. According to it, a method was constructed to generate K-distributed random numbers. Based on a series of independent random numbers that are uniformly distributed from 0 to 1, and then followed by some necessary operation, the method can be implemented. The method was also simulated and analyzed. The result reveals that the method constructed can generate the K-distributed random number effectively, and it is compacter and can be implemented easily.
