Each optimizing method has its strong point. On the point of view of math, optimizing for motor design is a process for extremum point for a nonlinear, restricted recessive function. Genetic Algorithms G.A.

从数学角度上来说，电机的优化设计就是一组非线性、有约束条件的隐性函数求极值问题，目前比较成熟的优化方法主要有遗传算法、模拟退火法与Tabu法等，其中以遗传算法应用最为广泛。

This article introduces three kinds of signal channel and gives some simulation results based on Rayleigh channel.

文中所有信号的仿真结果都是在Rayleigh信道下得到的。通过对MIMO传输矩阵的数学变换，我们可以得到一种比较简单的一对一的传输系统，这对理解MIMO的传输原理以及传输系统的仿真应用都有比较好的实用价值。
