GSM中GMSK调制信号的产生，在MATLAB中求图像纹理特征，滤波求和方式实现宽带波束形成。- GSM is GMSK modulation signal generation, In the MATLAB image texture feature, Filtering summation way broadband beamforming.

产生线性调频信号,可以是宽带，也可以是窄带信号。还有低通滤波器(A linear frequency modulated signal can be produced ,wideband or narrowband. There are also low-pass filters)
