采用LDPC编码对随机的二进制序列进行纠错编码和基带调制，在AWGN信道上进行传输，然后在接收端并采用合适的方式进行解调和译码，最后对纠错编码的性能加以分析。(LDPC codes using random binary sequence of error-correcting coding and base-band modulation, for transmission in the AWGN channel, and then at the receiving end and use the appropriate manner demodulation and decoding, error correction coding on the performance of the final analysis.)

利用迭代法实现图像阈值分割，简单好用，自带matlab图像直接运行(terative method to achieve image segmentation, easy to use, comes directly run matlab image)

An XPath package started shipping as part of Java 5, so we can use it from MATLAB. This is a simple example showing how to use XPath from MATLAB.

tdoa定位算（nlos情况）法用于无线传感器网络定位问题，可以求解定位算法的坐标值(talor algorithm for the localization problem in wireless sensor networks, localization algorithm can solve the coordinate value)

根据实测加速度振动信号，求取功率谱密度，为疲劳分析提供数据支撑(According to the measured acceleration vibration signal, the power spectrum density is obtained, providing data support for fatigue analysis.)

script for generting OFDM transmit waveform (loosely basedonIEEE 802.11 Aspecifications)

说明：  本程序对输入序列din实现DIT——FFT基2算法，点数取大于等于din长度的2的幂次(The program realization of the input sequence din DIT- FFT radix-2 algorithm, din length greater than or equal points to take a power of 2)
