simulate ber performance of example turbo code (rate-1/3, rsc = (1 5/7))

Practical matlab applications for engineers. contains objectives and examples from time domain representation of continuous and discrete signals to analog and digital filters.

基于matlab编写的数字高程模型DEM插值程序(a program for DEM interpolation)

The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most. This submission provides a tool for beginners to learn PID tuning.

分析信号谱峭度根据最相关性，提取敏感频段，进一步分析。(The kurtosis of the signal spectrum is analyzed according to the most relevance, and the sensitive frequency bands are extracted for further analysis.)
