本文主要是JTIDS的传输性能做了仔细的评估，并对其抗干扰做了一一的介绍。(The Joint Tactical Information Distribution System (JTIDS) provides jam-resistant digital communication of data and voice for command and control, relative positioning and identification. Many advanced technologies are adopted in JTIDS, such as frequency hopping, M-ary spread spectrum, error detection and correction.)

巴特利特波束成形基本代码,给初学者提供基本的参考，希望对大家有用(the bartlett beaformming code)

该程序可以实现信号的分形计算，从而求解出所求信号的分形函数，在信号非线性研究中有很重要的作用。(The program can calculate the fractal signal, thus solving the request signals a fractal function, the study of nonlinear signal has a very important role.)

说明：  设计一个理想通信系统，实现信息字符流的传输。 发射器： <1>将消息（字符串形式）编码成一个符号序列； <2>用脉冲成形将串符号序列转变成模拟脉冲信号； <3>将模拟脉冲信号调制到载波信号上。 接收器： <1>对接收的信号进行采样； <2>解调信号成基带信号； <3>将信号恢复成字符串。(Design an ideal communication system, the realization information transmission of character flow. Emitters: < 1 > will news (string form) coding into a symbol sequence < 2 > by using a pulse forming will string of symbols into a simulation pulse signal sequences < 3 > will simulate the pulse signal modulation to carrier signal. Receiver: < 1 > of received signal sampling < 2 > demodulation signal into baseband signal < 3 > will signal back into a string.)

生成白噪声信号：包括采样频率，最大和最小频率，时间长度，幅值等要求的信号。(Generated white noise signal: including sampling frequency, maximum and minimum frequency, duration, amplitude and other requirements of the signal.)

改程序可用于模拟凝固，再结晶，塑性变形微观组织演化(cellular compute_wait)

说明：  用最速下降法、共轭梯度法、牛顿法、BFGS求解范例目标函数.(Solving the case objective functions using the steepest descent method, conjugate gradient method, Newton method and BFGS method.)
