Matlab software that generates LDPC parity check matrix of rate 1/2 with the possibility of selecting the input output block dimension and performs BER evaluation of BPSK+LDPC transmission over AWGN channel.

matlab 与ENVI中数据格式转换，可以很好地实现两者之间的数据格式转换，包括enviwrite,enviread等(matlab with ENVI data format conversion, you can achieve a good conversion between data formats, including enviwrite, enviread etc.)

宽带波达方向估计的matlab仿真程序，使用tct算法求聚焦矩阵然后由music算法估计。(Broadband DOA estimation matlab simulation program, using tct algorithm seeking focusing matrix estimation algorithm is then music.)

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 (Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures, intermediate design and interpolation and decimation filter design. The filter design is using the window function method, according to the requirements of the design of window function, get the length of the window function. Then the interpolation, filtering, extraction, and finally obtain the variable wave file, sampling after the addition of contrast and polyphase decomposition results of two methods for convolution last direct convolution.)

在matlab上的Asift程序，在原有基础上有所改进，程序可以出色地实现图像的识别，匹配，效果相比SIFT，SURF等有大幅提高(In matlab Asift program improvements based on the original, the program can achieve excellent image recognition, matching, compared to the effect of SIFT, SURF, etc. have greatly improved)
