SAR图像处理算法，利用CS算法对回波信号进行处理成像。(SAR image processing algorithms, using the CS algorithm the echo imaging.)

一个Rayleigh衰落的clarke模型的问题,主要是信道仿真方面的,实用.(a Rayleigh fading clarke model that the main problem is the channel simulation aspects. practical.)

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several correction factors for other propagation conditions, such as: Antenna height and carrier frequency Suburban, quasi-open space, open space, or hilly terrain areas Diffraction loss due to mountains Sea or lake areas Road slope Hata derived empirical formulas for the median path loss (L50) to fit Okumura curves.

用matlab实现图像处理，尤其是图像分割方面的案例源代码。(Matlab image processing used to achieve, especially in case of image segmentation code.)

OFDM系统仿真，包含了发射、信道估计、接受等完整的OFDM系统仿真(his simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. )

Another good file for nothing

matlab的滤镜 包含有2个文件 作业(matlab filter contains two file operations)

说明：  主要是通过GA和PSO的全局搜索能力，用于改进BP网络的权值阈值(It is mainly used to improve the weight threshold of BP network)

MATLAB仿真OFDM过采样的东西，主要的星座图和每一个子载波上对应的星座图也被观察到。(MATLAB simulation OFDM sample things, the main constellation chart and each is the carrier of the corresponding constellation chart has been observed.)
