基于m序列的跳频序列生成
跳频通信信号处理中，最为基本的就是跳频序列生成，常用的生成方式有m序列、LG模型及混沌序列等方式，现给出常用线性移位寄存器生成m序列的代码，再由m序列生成跳频序列，现给出阶数可调的m序列生成方式以及基于此m序列生成的多用户且参数可调的跳频序列。

autocov computes the autocovariance between two column vectors X and Y with same length N using the Fast Fourier Transform algorithm from 0 to N-2.
The resulting autocovariance column vector acv is given by the formula:
acv(p,1) = 1/(N-p) * sum_{i=1}^{N}(X_{i} - X_bar) * (Y_{i+p} - Y_bar)
where X_bar and Y_bar are the mean estimates:
X_bar = 1/N * sum_{i=1}^{N} X_{i} Y_bar = 1/N * sum_{i=1}^{N} Y_{i}
It satisfies the following identities:
1. variance consistency: if acv = autocov(X,X), then acv(1,1) = var(X)
2. covariance consistence: if acv = autocov(X,Y), then acv(1,1) = cov(X,Y)

基于位平面的图像压缩
位平面编码是一种通过单独地处理图像的位平面来减少像素间冗余的有效技术。它将一副多级图像分解为一系列二值图像并采用几种熟知的二值图像压缩方法对每一幅二值图像进行压缩。位平面编码分为两个步骤：位平面分解和位平面编码，其中位平面的分解为核心步骤。

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)
