matlab code for digital modulations

ieee 的标准文献，学习ldpc码很有帮助的，可以参考参考，老外的东西还是比较权威的(ieee standard documents, helpful learning ldpc code, can refer to the reference, what foreigner, or more authoritative)

该程序可以进行扇形的短扫描重建，利用Parker加权函数。得到不错的重建效果。希望对大家有帮助。仅供参考！(This programme is a short-fan reconstruction.On the use of Parker weight function.I hope it will be useful.And the result of this programme is good.)

审定平均电平检测器(CMLD)CFAR，适用于多目标环境下的检测和定位(detector based on the censored mean level detector constant false alarm rate (CMLD-CFAR) technique)

说明：  分别建立pid控制与模糊PID控制的BLDC仿真模型，对比效果良好(BLDC simulation models of PID control and fuzzy PID control are established respectively, and the comparison results are good.)

该工具包是适用于地震数据的时频分析的工具包，对地震数据处理人员非常有用.(The kit is suitable for time-frequency analysis of seismic data toolkit for seismic data processing staff is very useful.)

说明：  实现对小孔的高斯滤波，边沿提取和半径测量(Small holes to achieve the Gaussian filtering, edge extraction and radius measurement)

MATLAB的函数大全，基本上所有的内置函数都有了。(MATLAB function Daquan, basically all have a built-in functions.)

本文利用软件相移技术得到相互正交的参考正弦波信号；通过互相关算法，完成了软正交矢量型LIA相关器的具体实现；利用该方法实现了对微弱信号幅值和相位的检测，有效地抑制干扰，减少了硬件电路成本。通过Matlab仿真，验证了该算法具有一定的优越性。(In this paper, the software technology is orthogonal to the phase shift of the reference sine wave signal through cross-correlation algorithm to complete the implementation of soft orthogonal vector LIA correlator achieved using this method for detecting a weak signal amplitude and phase, effectively suppress the interference and reduce the cost of the hardware circuit. By Matlab simulation show that the algorithm has certain advantages.)
