sampling theorem description

Low-density parity-check (LDPC) codes have recently emerged due to their excellent performance. However, the parity check (H) matrices of the previous works are not adequate for hardware implementation of encoders or decoders. This paper proposes a hybrid parity check matrix which is efficient in hardware implementation of both decoders and encoders. The hybrid H-matrices are constructed so that both the semi-random technique and the partly parallel structure can be applied to design encoders and decoders.

gnss跟踪算法仿真，使用matlab编译，文件类型为.m(Tracking algorithm simulation)

This report is written in fall semester of 2004 and spring semester of 2005 at Aalborg University, at the institute for Electronic Systems, department for process control under the study council for Electronic and Informations Technology.

视频的关键帧计算，和关键帧提取，附有实验报告(Video key frame basis, and key frame extraction, with test report)

说明：  用于广播系统发射机的数字中频调制采用64QAM的方式，使用matlab中的altera dsp builder实现。(64QAM modulator, used in broadcast system digital IF modulation.)

此程序的功能为对采集到的信号进行小波阈值去噪，阈值为改进阈值。(the program is used for wavelet denoise)

实现谱减法，很实用，有四种图形显示，带颜色的，可以直接调用，需要voicebox工具包(o achieve spectral subtraction, it is practical, four graphic display, with color, you can directly call, you need the voicebox toolkit)

基于支持向量机的语音信号端点检测，主要是去掉首位的噪声。(Voice signal endpoint detection based on support vector machines, mainly to get rid of the first noise.)
