本函数实现对16位位深医学灰度图像的窗宽窗位调节-this function to achieve 16-bit gray images medical deep window width and window-conditioning

This program simulates the bit-error-rate (BER) performance of OSTBC with L=4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation- 16 QAM with gray c

注意：本程序中,每点击一次“增加亮度”,图像灰度提升16-Note: in this program, every click on the increase brightness , the image gray level 16
