基于Alamouti的STBC-OFDM系统性能分析(Based on Alamouti' s STBC-OFDM system performance analysis)

说明：  利用PTS技术降低峰均比，并作出与未使用降低PAPR技术的CCDF对比图形(Comparing with OFDM system without PAPR reduction techniques,figure the CCDF using PTS technique.)

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )

实现对肌电信号的预处理 主要是设计了两个滤波器，高通滤波器和500Hz低通滤波器，带宽可调(emg filtering )

基于MATLAB软件的有关雷达杂波的很多个程序，相信对初学者很有帮助(MATLAB-based software clutter on the radar of a lot of procedures, I believe very helpful for beginners)

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

基于谱聚类分区的matlab程序实现，可以运行。程序给出的是118标准IEEE算例。结果用图形显示很直观，有需要的可以借鉴。(Matlab program based on spectral clustering partition, you can run. The program gives 118 standard IEEE example. The results are graphically displays very intuitive, need to learn from.)

For tasklet and interrupt structs defines.

用于实现上面应用程序的相关数据集.是matlab数据文件格式的(used to achieve the above applications related data sets. Matlab is the data file format)
