IP1101 circuit application

运用前推回推法进行配电网潮流计算。附有33母线系统数据，以供检验。程序没有考虑电容器、分布式电源，以及弱环网的影响。(Before using push back push power flow calculation method. With 33 bus system data for testing. The program does not consider the capacitor, distributed power, and the impact of the weak ring network.)

无线通信预留信道一维马尔科夫链间接推论法(1D Markov chain- indirect inference)

,在强干扰中提取信号,不仅要求有一定的信噪比,而且必须对信号作恒虚警处理.在自动检测系统中,对一定的检测门限来说,当干扰电平增大几分贝,虚警率就会大大增加,致使显示器画面饱和或计算机过载,这时即使有足够大的信噪比,也不可能做出正确的判决.为此在自动检测雷达中,必须具备恒虚警处(, extracting signal in strong interference, not only requires a certain signal-to-noise ratio, and must make constant false alarm processing for signal. In the automatic detection system, for a certain detection threshold, when the noise level increases, a few decibels will greatly increase the false alarm rate, led display screen saturated or computer overload, even if there is enough SNR at this moment, it is impossible to make the right decision. Therefore in the automatic detection of radar, must have a constant false alarm)

加性噪声以及jakes信道模型的代码，对新手可以起作用。(Additive noise and the code of the jakes channel model can play a role for novices.)

这是我老师给的一些代码，在此借用了，呵呵(I m a new student )
