此程序为混有高斯白噪声的多径信道下的仿真，参数根据需要可以再次优化(This procedure mixed with white Gaussian noise multipath channel simulation, the parameters required can be re-optimized)

常用的上下行信道模型，写的很清晰，适合入门的人看。(Commonly used up and down the channel model, written in a very clear, people will look for entry.)

利用牛顿拉夫逊法进行电力系统潮流计算。附带IEEE-14、30节点数据。(Newton Raphson power flow calculation method. Comes with IEEE-14,30 node data.)

HMC5883磁力计使用前必须进行校准，这个matlab程序用来拟合磁力计的数值，然后得出补偿值(HMC5883 magnetometer must be calibrated before use, the procedure used to fit the numerical matlab magnetometer, and then come to the compensation value)

这是一个dynare code可以用来求DSGE中的稳态解和均衡解(dynare code for a simple task)

Bluetooth is a wireless technology that allows computers, phones, headsets, PDA s and other devices to wirelessly communicate over short distances (up to 33 feet). Bluetooth uses radio waves (in the 2.4 GHz range), and is designed to be a secure, low power and inexpensive way of connecting and exchanging information between devices without the need for wires or cables to link devices together.
