Jafarkhani differential STBC matlab procedure, at different signal to noise ratio, the system compares the SER and BER. The use of 2-fat one admission, Rayleigh fading channel

LDPC decoder for Chinese DTV standard. This code works for all code rate,only need to change is Paritycheck matrix.I have tried with 1/2 code rate.

AGC系统的输入输出功能与中频放大器闭环增益的关系曲线，simulink模型。(AGC system input and output functions and IF amplifier closed-loop gain curve, simulink model.)

本程序对阴影处理效果不佳，但思路清晰明了，适合初学者参考。">

说明：  提出了一种改良的可应用于3GPP-LTE控制信道的信道估计和检测的方法。(A modified control channel can be used in 3GPP-LTE channel estimation and detection methods.)

这是数学专业的数学建模的课程设计，很有用啊，希望大家踊跃下载啊(This is the mathematical modeling mathematics curriculum design, very useful, ah, ah hope you actively download)

说明：  基于matlab的直接序列扩频系统抗干扰性能仿真(Simulation of Anti-jamming Performance of Direct Sequence Spread Spectrum Communication System Based on MATLAB)

this gives you detailed abt the active power filter and its used. You can mitigates the harmonics by using a active power filter.

合成地震记录是用声波测井或垂直地震剖面资料经过人工合成转换成的地震记录（地震道） 合成记录的制作是一个简化的一维正演的过程，合成记录F(t)是地震子波S(t)与反射系数R(t)褶积的结果。(Synthetic seismogram is sonic or vertical seismic profile data after conversion into synthetic seismograms (seismic trace) the production of synthetic seismogram is a simplified one-dimensional forward modeling process, synthetic seismogram F (t) is the seismic wavelet S (t) and the reflection coefficient R (t) the convolution results.)

时间序列建模AR（1）后的卡尔曼滤波程序，整个过程非常详细，里面自带一组数据。(Time series modeling AR (1) after the Kalman filtering process, the entire process is very detailed, which comes with a set of data.)
