BPSK EGC分集程序，仿真了分集带来的性能增益(EGC diversity gains)

可以得到很精确的幅值、频率、相位估计，相控阵天线的方向图（切比雪夫加权），用于信号特征提取、信号消噪，数据模型归一化，模态振动，包括最小二乘法、SVM、神经网络、1_k近邻法,IDW距离反比加权方法。( You can get a very accurate amplitude, frequency, phase estimation, Phased array antenna pattern (Chebyshev weights), For feature extraction, signal de-noising, Normalized data model, modal vibration, Including the least squares method, the SVM, neural networks, 1 _k neighbor method, IDW inverse distance weighting method.)

主要用于各种的状态估计滤波，在目标跟踪和定位方面有很强的应用，在实际项目中有应用的范例(Mainly used for a variety of state estimation filter, target tracking and positioning in a strong application in practical projects are examples of applications)

FIR滤波器设计中的凯撒窗函数设计，最后有对应系数产生(FIR filter design in the design of the Kaiser window function, and finally there are the corresponding coefficients have)

Matlab codes for calculating RMS Value and finding roots.

集群通信随机接入仿真，主要是针对集群用户接收与普通用户接收的对比（直方图），集群用户正确接收率、普通用户接收率，总的误判率。(Cluster communication random access, cluster users and ordinary users access contrast (histogram), cluster users receive the accuracy and ordinary users receive the accuracy rate of miscarriage of justice problems.)

说明：  合成孔径雷达的RD算法实现，非常有用的算法(Synthetic aperture radar RD algorithm, a very useful algorithm)

摄影测量后方交会、前方交会、相对定向、绝对定向、光束法平差等。 (Photogrammetric resection, forward intersection, relative orientation, absolute orientation, bundle adjustment and so on.)

In this section, the PAPR performance of the proposed algorithms is shown. To evaluate the PAPR performance, the CCDF is employed. The specification detail of simulation parameters is given in TABLE I. In Fig. 5 is shown the PAPR with a PTS method (U = 8) and conventional PTS (U = 4) are improved 4.3 dB and 2.6 dB from ordinary MIMO-OFDM signal when CCDF = 10− 4 respectively and Fig. 6 is shown the PAPR with an optimal PTS method in case of 128 subcarriers.
