说明：  OFDM信道仿真源代码，基于matlab环境开发(OFDM channel simulation)

基于MATLAB仿真程序，使用牛顿迭代法，在已知时延先验信息的基础上，对目标实现无源定位。 程序内还包含符号迭代和等值线绘图等角复杂代码。希望对研究无源定位的同志有所帮助。(MATLAB-based simulation program, using Newton s iterative method, the known delay on the basis of prior information on target to achieve passive positioning. Symbols within the program also includes iteration and contour drawing isometric complex code. Hope the study of passive location comrades help.)
