channel estimation of ofdm using pilot based

[Numerical analysis]_ This algorithm computes the root of a function by the Wijngaarden_Dekker_Brent method.

abaqus umat 用户子程序开发。动力显式模拟。完全编码加解释。(abaqus umat user subroutine development. Dynamic explicit simulation. Complete coding explanation.)

说明：  正态总体参数的检验,调用ztest和ttest函数(Inspection normal population parameters)

遮挡因子及角闪烁模型 输入：时延tau，脉冲重复周期tr，脉宽tp 输出：遮挡因子F(Occlusion factor and angle scintillation model input: the delay tau, the pulse repetition period tr, pulse width tp output: occlusion factor F)

one of the best ways to have a blind channel estimation is using a precoding after before IDFT operation in OFDM systems,this simulation shows the precoding infulence on the system.

BPSK信号衰落的仿真；计算BPSK平均，分散与矢量数据的标准差(Evaluation program of fading counter based BPSK transmission scheme calculate mean, dispersion and standard deviation for the vector data)

研究高超声速飞行器在纵向的运动情况，对系统的速度和飞行高度进行仿真分析，我们将对在不同的 、 值的条件下分析出系统的最优性能(The longitudinal motion of the hypersonic vehicle is studied, and the system speed and flight height are simulated. We will analyze the optimal performance of the system under different conditions and values.)
