说明：  高级信道ＱＰＳＫ的设计与仿真，改善了信道性能，对仿真数据可有效汇总，输出理想比现实比较曲线(Advanced Channel Design and Simulation of QPSK, the channel to improve performance, the simulation data can effectively aggregate, more than reality curve of the ideal output)

MATLAB做的不错的人脸识别的程序，希望大家能能受用，-color ，经测试可直接使用。 (Face recognition program MATLAB to do good, and I hope that we can be able to benefit from-color has been tested and can be used directly.)

到达时间差（TDOA）源位置估计 -------------------------------------------------- ---------- 使用麦克风信号和自由场模型之间的延迟源位置估计。 TDOA_pairs.m 估计延迟（相对于通道1）通过互相关在时域中。 TDOA_pairs_GCC.m 估计在频域中的延迟（相对于信道1）。采用广义互相关 和SCOT或PHAT（或没有）的均衡。 PHAT的建议，以避免因周期分量的含糊之处。 TDOA_to_sourcepos.m 估计源位置（距离和垂直RESP。水平偏移量）从之间的延迟 阵列麦克风信号。假设一个自由场。(Direction of arrival (DOA) estimation ------------------------------------- Direction-of-arrival estimation with a free field, far field model.
