认知无线电中的波束成形MATLAB代码。可以根据拓扑众不同位置的节点调整天线的发射功率和角度。师兄博士毕业论文里的代码。希望能有帮助(Matlab code of beamformer in Cognitive Radio. it can regulate and adjust the transmitting power and angle of antenna, which belong my laboratory mate s PHD thesis. It may help you.)

无线通信系统中的空时编码的仿真程序。多天线发送，多天线接受系统。衰落信道。(wireless communication systems and space-time coding the simulation program. Multi-antenna sending, receiving multiple antenna system. Fading Channel.)

灰度图像灰度经过按位混沌加密后再对其混沌置乱变换，阀值判断其迭代次数，达到预期加密效果(After a bit gray gray chaotic encryption by scrambling after its chaotic transformation, determine the threshold number of iterations to achieve the desired effect of encryption)

通过重心法确定光斑图像的中心。根据个像素的灰度值和所在的位置乘积和总面值作比，进而求得重心。(Through the center of gravity method to determine the center of the image spot. According to the gray-scale pixel value and the location of the product and the total for more than face value, and then get the focus.)
