用matlab实现ami/cmi/hdb3编码(achieving ami/cmi、hdb3 using matlaa)

用于基于移动通信系统的室外定位中的非视距传播中的Chan定位算法，泰勒定位算法，以及基站的选取算法。(For outdoor positioning based mobile communications system in the NLOS propagation of Chan location algorithm, Taylor location algorithm, and the algorithm to the base station.)

说明：  matlab实例应用，主要列举了matlab的常用功能，绘图、矩阵运算等等(matlab example application, the main common features listed matlab, graphics, matrix operations, etc.)

非常有用的遗传算法程序，包含主程序和子程序，用matlab编写，适合学习和改编，里面有详细的注释。(Very useful genetic algorithm program, including the main program and subprograms, written matlab, suitable for learning and adaptation, there are detailed notes.)

计算SENSE重建图像中的g-factor,这是并行磁共振成像SENSE算法的关键一步(G-factor is the metric to quantify the amplificaiton of noise power in reconstructing SENSE accelerated image. The detail was presented in Pruessmann s 1999 Magn. Reson. Med. paper. In theory, g-factor is the pixel-by-pixel ratio of the image variance between the SENSE reconstructed image and un-accelerated image. And g-factor depends on: (1) the k-space data trajectory (2) coil sensitivit profiles (3) noise covariance matrix of the array coil)
