在Windows95下PC机和单片机的串行通信。 基于32位操作系统Windows95的工业控制PC机和单片机间的串行通信，给出了用VC＋＋5．0和PL／M－96语言编写的串行通信程序(Under the PC in the Windows95 and single-chip serial communication. 32-bit operating system based on the Windows95 machine and industrial control PC serial communication between the single-chip, is given by VC++5.0 and PL/M-96 language serial communication program)

说明：  qpsk的调制解调，使用simulink实现(QPSK modulation and demodulation, using Simulink to achieve)

说明：  EEMD分解信号，可将信号分解为不同频率的固有模态分量，方便后续分析(EEMD decomposition signal)

说明：  Performance Evaluation of DWT

说明：  CDMA技术的原理是基于扩频技术，即将需传送的具有一定信号带宽信息数据，用一个带宽远大于信号带宽的高速伪随机码进行调制，使原数据信号的带宽被扩展，再经载波调制并发送出去。CDMA系统仿真，初学者(CDMA system simulation)
