熟悉非高斯色噪声的产生过程，并对其进行参数估计。 产生一高斯噪声，让其通过一线性系统，再得到符合需要的对数正态分布。 (Familiar with the process of non-Gaussian colored noise generated, and estimated its parameters. Generate a Gaussian noise, so that the linear system to meet the needs of the lognormal distribution.)

实序列FFT快速算法，用N点FFT计算2N点实序列的FFT，比直接进行2N点FFT运算减少一半运算量。(Real sequence FFT fast algorithm, using N-point FFT calculation 2N point real sequence of FFT, than the direct 2N-point FFT computation halved.)

巴克码（相位编码脉冲信号）的波形、频谱和模糊函数的计算。((Phase-coded pulse signal) is calculated waveform, spectrum and ambiguity function Barker code.)

提出了采用小波包的方法对供暖双吸式离心水泵轴承振动信号进行去噪和提取表征 相应轴承故障的频带能量 并采用 BP 神经网络进行训练和故障识别 通过 MATLAB 进行了仿真经试验验证该方法能够有效地识别出轴承故障(The wavelet package is adoptted to De-noise and extract band energy that represent bearing fault. and the BP neural network is adopting to train and recognize faults. Through MATLAB simulation, After the test validate the method, it can effectively recognize the bearing fault.)

本程序主要是用于求解目标函数的凸优化问题。(This procedure is mainly used to solve the objective function of the convex optimization problem.)
