LDPC码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

此程序用语捷联惯性导航系统中姿态，经度，纬度，速度等参数的计算。(This procedure terminology strapdown inertial navigation system in the posture, longitude, latitude, speed and other parameters of the calculation.)

说明：  多分类算法 matlab源代码 multiclassify(multiclassify)

dividevec()用来重新随机抽取上述三种分类的数据，原来的顺序被打乱(dividevec () is used to re-random sample of the above three categories of data, the original order has been disrupted)

灰色模型GM(1,1)的matlab代码(Gray model)

高斯列主元消去、直接分解（LU）matlab小程序(Gauss pivot column, LU decomposition matlab applet)

有关OFDM时域和频域同步的硬件实现，在FPGA,DSP和ASIC上实现，并做了对比。(On the OFDM time domain and frequency domain synchronization hardware implementation, in the FPGA, DSP and ASIC to achieve, and has done a comparison.)

用MATLAB编写的EMD（经验模态分解）例程。实现了Hilbert黄变换、经验模态分解等理论算法，里面包含具体应用。(It is EMD sample codes. The Hilbert-Huang transform is coded by Matlab. And the EMD samples are included.)

雷达信号检测和信息提取:根据雷达接收到的信号检查是否含有目标反射回波，并从反射回波中测出有关目标状态的数据。信号是信息的载体，信息是信号的内容。雷达工程界习惯于把雷达信号检测和信息提取的具体实施称为雷达信号处理，并把这种处理与测出的数据的处理合称为雷达信息处理。技术科学界最初把采用数理统计工具解决这一类信息处理的理论问题称为检测理论，后又称为检测与估计(Radar signal detection and information extraction, according to the received radar signal check whether contain the target echo, and measure the echo data on target state.Signal is the carrier of information, the content of the information is a signal.Radar engineering is used to the specific implementation of the radar signal detection and information extraction called radar signal processing, and the processing and the processing of measured data as radar information processing.Technology of the scientific community initially put the use of mathematical statistics tools to solve this problem is known as a kind of information processing theory testing theory, also known as the detection and estimation)
