I am simply extracting three types of features from the wavelet transform coefficients, these include: energy, variance and waveform length. You can modify and extract any types of features as you need. ** You need the wavelet toolbox to run this code.

五位巴克码相位编码信号仿真以及时域、频率特性研究(Simulation of Five Barker Code Phase Coded Signals and Study of Time Domain and Frequency Characteristics)

本论文为自动化系专业毕业设计论文,介绍了一种双数字信号处理器（DSP）最小控制系统，通过此系统实现永磁同步电动机的矢量控制设计。(papers for the automation system design graduation thesis, introduced a dual digital signal processor (DSP) is the smallest control system, through this system to achieve permanent magnet synchronous motor control vector design.)

添加噪声处理，解耦，恢复原信号，代码里有很完整的注释和解释。( Add noise processing, Decoupling, restore the original signal, )

说明：  调相的matlab实现，实现调相的调制解调(PM)

针对无线射频识别(radio frequency identification，RFID)系统的多标签碰撞问题，在分析RFID标签编码规则的基础上，提出根据标签编码规则进行标签分组和标签预淘汰的方法，在读写器识别的初始阶段根据特定的规则淘汰部分标签，从而减少系统工量，提高系统工作效率.实例证明：在不增加标签结构复杂度的基础上，充分利用已有的有效信息能够有效减少阅读器的查询次数和系统的总通信量．(For radio frequency identification (radio frequency identification, RFID) system is a multi-tag collision problem, based on the analysis of the RFID tag encoding rules based on the proposed label grouping and labeling pre-elimination method according to the label encoding rules identified in the initial reader phase-out of the label according to specific rules, thus reducing the amount of system engineering, to improve system efficiency examples demonstrate: the label without increasing the complexity of the structure on the basis of full and effective use of existing information can be effective in reducing the number of queries and reader total traffic of the system.)
