基于matlab编程，给定几对初值，利用ode求解奔月的轨道示意图(Matlab-based programming, given a few of the initial value, the use of ODE solving flying to the moon orbit diagram)

傅里叶变换功能的实现，虽然是非常见得的频率成分，但是还是实现了基本的傅里叶变换功能，并不是matlab自带的fft函数。实现了频谱分析可视化。(Fourier transform function, although it is very frequency components appear, but still achieve the basic function of the Fourier transform, comes not matlab fft function. Achieve a spectral analysis visualization.)

这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT， 上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模 块，并统括系统性能的仿真验证了系统设计的可靠性 ( This is a relatively complete simulation of OFDM communication system design, including coding, modulation, IFFT, upper and lower frequency, Gaussian channel model, FFT, PAPR suppression, various synchronization, demodulation and decoding module block, and system including the simulation of system performance reliability of system design)

将三维图像分割为由3*3*3体素组成的立方体实现更细化的分析(The three-dimensional image is divided by 3* 3* 3 cube of voxels composition to achieve a more detailed analysis)

二元CPFSK的 不开根升余弦成型函数调制及解调, 解调法采用了8倍采样的最终点解调.(Binary CPFSK not open root raised cosine shaping function of modulation and demodulation, the demodulation method using 8 times the final sampling point of demodulation.)
