2-D_Diffusion

最速下降法，用于计算机，数值方法的实现，需调试再用，谢谢大家(steepest descent method)

Code to simulate 2theta-omega scans for InGaN/GaN films

The is a fully functional GPS SDR. It can accept real data or simulate its own data. It performs correlation, signal parameters discrimination, and loop filtering both code and carrier with the option of carrier loop aiding of the code loop. There are many support functions such as the numerically controlled oscillator, coarse acquisition code generator that are in the archive. This does not include the acquisition engine, just the channel tracking state machine. The also outputs carrier phase measurements and modulo 1ms pseudorange.

说明：  在低信噪比下，基于双稳随机共振的微弱信号检测(Weak signal detection based on bistable stochastic resonance at low signal-to-noise ratio)

说明：  利用matlab实现QPSK,16QAM,64QAM三种调制方式的调制和解调。(Using matlab to achieve QPSK, 16QAM, 64QAM modulation of three modulation and demodulation.)

一个matlab 工具包，可以解决非线性的优化问题，很好用(A matlab toolkit, you can solve the nonlinear optimization problem, and good use)

系统的结构参数和负荷情况都已给定时，调节可利用的控制变量(如发电机输出功率、可调变压器抽头等)来找到能满足所有运行约束条件的，并使系统的某一性能指标(如发电成本或网络损耗)达到最优值下的潮流分布。(Optimal power flow(OPF) is a fundamental tool in power system planning and operation.)
