完整清晰的描述了光通信中QPSK,16QAM的调制，matlab代码仿真通过(Clear and complete description of the optical communication QPSK, 16QAM modulation, matlab code emulation by)

说明：  设计一个模糊PID控制器,以及倒车系统simulink系统，使其可是实现对倒车系统的的优化控制。(Design a fuzzy PID controller, and the reversing system simulink system, so that it can achieve optimal control of the reversing system.)

分数阶Fourier变换，直接根据公式实现，没有用快速算法(Fractional Fourier transform, directly under the formula to achieve, not with the fast algorithm)

A generalized Richardson extrapolation routine that can perform multiple extrapolation steps, can accommodate arbitrary leading error terms, can handle any uniform refinement scheme (e.g. h/2, h/3, h/5, etc), and can report a full extrapolation table including comparing against a known good solution. Able to handle vector inputs. Compatible both with MATLAB and Octave. Includes Octave-style unit tests.

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 (Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures, intermediate design and interpolation and decimation filter design. The filter design is using the window function method, according to the requirements of the design of window function, get the length of the window function. Then the interpolation, filtering, extraction, and finally obtain the variable wave file, sampling after the addition of contrast and polyphase decomposition results of two methods for convolution last direct convolution.)

说明：  主成分分析和独立成分分析,分别处理降维问题和盲信号分离问题(Principal component analysis and independent component analysis, dimensionality reduction, respectively, deal with the problems and blind signal separation)
