LDPC code decoding method based on log domain,it s very useful for beginner to simulate. Meanwhile the block length can be changed by parameter u.

LCL滤波器在现代的可再生能源行业的应用十分的普遍，可以有效、经济地确保和提高从能源到电网的馈电质量。滤波器用于过滤逆变器工作产生的开关频率。在达到目标畸变水平的同时，滤波器还会节约比较可观的成本。LCL滤波器的典型特点是损失小、体积小、重量轻、电容大。(LCL filter in the application of modern renewable energy industry is very common, can be effectively and economically to ensure and improve the quality of energy to the grid feed. This filter is used to filter the inverter switching frequency. The filter will reach the target distortion level at the same time, considerable cost savings. LCL filter typically characterized by loss, small size, light weight, large capacitance.)

这个MATLAB程序是用于对音频信号进行降噪处理，可以在这个软件上进行更改实现自己的功能。(The MATLAB program is used to handle audio signal noise reduction, you can change the software realize the functions of their own.)

小波分析及其应用的matlab程序，都是示列，对于学习利用matlab进行小波分析很有用(Matlab wavelet analysis and its application procedure are shown out, for learning using wavelet analysis is useful matlab)

用matlab来制作卫星绕地球做周期运动的动画，改变卫星的角速度的初值，可以画出圆形，椭圆形，逃逸轨迹。(Using matlab to produce satellites orbiting the earth to do periodic motion animation, change the initial angular velocity of the satellite, you can draw round, oval, escape trajectory.)

VBLAST的基于QR的检测算法的误比特曲线。(VBLAST QR detection)

For an AR(p) model that has been fitted with ARFIT, [Aerr,werr]=ARCONF(A,C,w,th) computes the margins of error Aerr and werr such that (A +/- Aerr) and (w +/- werr) are approximate 95 confidence intervals for the elements of the coefficient matrix A and for the components of the intercept vector w. The input arguments of ARCONF are output of AR.
