附件包括了运用mimo技术实现的ofdm系统，其中包括信道的创建，调制解调技术，还有相关指导文档(Accessories include using mimo ofdm systems technology implementation, including the creation of the channel, modulation and demodulation techniques, as well as the relevant guidance documents)

This is the Matlab program I developed for power flow. Program can handle system with or without distributed generation (DG).

This is the matlab code of improved LEACH. It describe the raffinement of LEACH protocol

包括：使用控制变量蒙特卡洛法和一般蒙特卡洛法的欧洲期权看涨价格程序；使用蒙特卡洛计算定积分；使用B-S公式计算期权价格。 ( Including: European call options price procedure using control variable Monte Carlo method and general Monte Carlo method using Monte Carlo calculation of definite integral use the B-S formula to calculate the price of option.)

The relationship of voltage gain to modulation index is analyzed in detail and verified by simulation and experiment

说明：  利用matlab中随机森林工具包数据进行预测(RF toolkit data in matlab was used for prediction)

模糊和PID混合温度控制器，在小偏差时使用pid控制，大偏差时使用模糊控制，通过开关来切换。本室里具有一定参考价值(Fuzzy and PID temperature controller hybrid, a small deviation in the use of pid control, the use of large deviation of fuzzy control, through the switch to switch. This room has a certain reference value)

噪声背景下的语音端点检测和语音增强算法，在信噪比很低的强航空噪声背景下，(aviation noise background voice endpoint detection and voice enhancement algorithms, and very low signal to noise ratio in the strong aviation background noise, particularly effective)

这是一个实现FM调制的信号去噪均衡程序，你可以理解FM调制的原理，同时理解均衡去噪的原理(This is an FM modulated signal denoising achieve a balanced program, you can understand the principles of FM modulation, while understanding the principles of balanced de-noising)
