信号经过两个独立的信道传输，两个信道的信道复增益分别为 和 。 是独立同分布的复高斯随机变量，实部虚部独立、均值为0，实部虚部的方差都是1。采用某分集技术后输出的信噪比为 ，其中 是常数， 是在 之间均匀分布的随机变量。请就不同的 、 ，用仿真的方法画出 的累积分布函数。(signal after two independent Channel Tunnel, Channel 2 Channel Minute respectively, and gain. Independence is the same complex Gaussian distribution of random variables, is the imaginary part of the Department of independence, mean 0 and the real part of the imaginary part is a variance. Using a diversity of the output signal-to-noise, which is constant, is the uniform distribution between random variables. Please different, and simulation methods paint the cumulative distribution function.)

CMM是指“能力成熟度模型”，它是对于软件组织在定义、实施、度量、控制和改善其软件过程的实践中各个发展阶段的描述。CMM的核心是把软件开发视为一个过程，并根据这一原则对软件开发和维护进行过程监控和研究，以使其更加科学化、标准化、使企业能够更好地实现商业目标。此外还是化妆品的名字。 (CMM refers to the Capability Maturity Model , which is for software organizations define, implement, measure, control and improve their software processes describe the practice in all stages of development. CMM is the core software development as a process, and in accordance with the principles of process monitoring and research on software development and maintenance, to make it more scientific, standardized, enabling enterprises to better achieve business goals. Additionally or cosmetic name.)
