It simulates a simple circuit analysis phasors of current and voltages.

实现多用户MU，通过两次预编码来消除用户间干扰和流间干扰，同时这种处理极大简化了接收机复杂度。(MU-MIMO 。 the first precoding ：ZF-BD the second precoding ：ZF or MMSE)

画一个三维的抛物线，供你参考，希望有所帮助，多多交流(Draw a three-dimensional parabolic, for your reference, hoping to help, a lot of communication)

HBM实行快速傅里叶变换，这是谐波平衡法中的一个重要的环节(Harmonic Balance Method is a very useful method in solving rotor dynamics, and fast fourier transform is an important part in it)

基于matlab的直接序列扩频通信系统的设计与仿真，在Matlab2012b上(Design and simulation matlab direct sequence spread spectrum communication system, on the Matlab2012b)

大学生数学建模的书籍以及训练习题，和答案，应该对参赛的选手有一定的帮助。(Mathematical modeling of books and training exercises, and answers for participating players should have some help.)

说明：  matlab 闭曲线B样条的拟合，算例可直接使用，使用时只需要修改nq文件或者aline文件中的u1即可，也可定义u1后直接run aline(matlab closed B-spline curve fitting, numerical example can be used directly, using only a need to amend the nq documents or document aline can u1, u1 can be defined also directly run aline)
