图像的二值化,不使用Matlab自带的语句处理，使用的是自己的编程语句。(Binary image, do not use Matlab s own statement processing, using their own programming statements.)

MATLAB几何变换，可以方便了解到所变换的几种形式(MATLAB geometric transformations, you can easily understand the transformation of several forms)

运用matlab,采用QPSK调制与解调，包括串并转换，傅立叶变换与逆变换，信道估计（采用LS准则），多普勒频移等模块，内容清晰明了。(Use matlab, using QPSK modulation and demodulation, including string and conversion, Fourier Transform and inverse transform, channel estimation (LS criteria used), Doppler frequency shift modules, content clarity.)

TD—SCDMA物理层的调制解调仿真，本程序忽略了很多细节，只把最重要的调制解调过程仿真。(TD_SCDMA physics level simulation)
