QPSK-Modulation-and-Demodulation

分数阶PID比一般PID多了2个可调参数，实现了常规PID所无法实现的控制功能，并且更精确有效(Fractional PID PID more than two adjustable parameters, and can not be achieved by the conventional PID control functions, and more accurate and efficient)

空时编码的matlab仿真程序，其中包括almouti，空时分组码仿真，空时格行码的设计仿真，不同信噪比下的比较，码长天线数的比较(the simulations of space-time coding are include in this rar file, adhered with the almouti scheme, space-time block cade sheme and space-time trill code sheme. )

学习笔记，是关于一些图形绘制以及编写函数实现各种功能 仅供参考(matlab note)

最新版的matlab gauge工具箱，目前很多版本无法自带安装，直接解压后添加到toolbox目录下即可（附带很多有用控件）(The latest version of matlab gauge toolbox, many versions of currently installed not own, directly unpacked directory can be added to the toolbox (with a lot of useful controls))

adaptive voice activity detector for speaker verification

说明：  ofdm的同步方法的参考文献，讲述了各种不同的参考文献的方法。(The synchronization method ofdm references about a variety of different methods References.)

normalization of iris using pupil

说明：  bilstm saelstm lstm 使用了五种函数进行了对比，有数据算例。可以多输入，也可以单输入。(Comparison of five neural network algorithms)
