a useful matlab code

pwm单极性调制和双极性调制电路，开环电路(Pwm unipolar modulation and bipolar modulation circuit, open loop circuit)

本程序利用中值滤波对加噪图像进行处理，并取得了很好的效果。(This procedure using median filter to process the images with noise, and have achieved good results.)

说明：  【 摘 要】 提出了一种基于负熵的快速不动点1 C A算法， 介绍了负熵的定义和如何将其用作代价函数度量混合信号的非 高斯性。 详细介绍了基于负熵的固定点准则以及简化算法。实验选取 3个非高斯向量作为信号源进行 Ma t l a b分离仿真， 结果显示 分离效果良好。 (Abstract Based on the rapid Negentropy 1 CA fixed point algorithm, introduced the definition of negentropy and how to measure its cost function for mixed-signal of the non-Gaussian. Described in detail based on the fixed-point Negentropy criteria and simplify the algorithm. Experiment to select three non-Gaussian vector as a signal source separation Ma tlab simulation results showed good separation efficiency.)

说明：  独立成分分析算法降低原始数据噪声，并提取特征值，非常有用得数据去噪程序。(Independent component analysis algorithm reduces the raw data noise, and extract characteristic value, is more helpful data denoising procedure.)

说明：  加循环前后缀和升采样程序，插入循环前后缀是将每个OFDM符号的前32个数据放到符号尾部，将每个OFDM符号的后32个数据放到符号头部，升采样是通过中间插零的方式实现(Cycle before adding the suffix and lift sampling program, insert the loop before the suffix is ??the first of each OFDM symbol data into the symbolic end of 32, after each OFDM symbol data into the symbols of 32 head or through the middle of the sampling way to achieve zero insertion)

说明：  放大转发（DF）matlab环境下的通信系统仿真(Amplify and forward (DF) Matlab environment communication system simulation)

说明：  用不同模板对图像进行高斯噪声、椒盐噪声进行中值滤波均值滤波(Gaussian noise, salt and pepper noise are filtered by different templates, and mean filtering is used)
