说明：  opnet学习入门视频教程 这个对初学者很有用的(opnet Getting Started video tutorial to learn this very useful for beginners)

FBMC的各个模块的代码实现，适合FBMC入门参考。(Code Implementation of Each Module of FBMC)

matlab与tracepro通信接口文件(Working with Matlab and TracePro through Dynamic Data Exchange)

这是一个扩频通信系统的通信系统建模的MATLAB仿真程序,里面有详细的通信系统建模的步骤,希望对大家有所帮助 (This is a spread spectrum communication system of communication system modeling of MATLAB simulation program, there is a detailed communication system modeling steps, hope to be helpful to you )

DQPSK调制的程序,用Simulink的C函数实现()

qpsk完整解调，包括载波同步，位同步采用迟早门，载波同步采用判决反馈(qpsk complete demodulation, including the carrier synchronization, bit synchronization using the door sooner or later, the use of decision feedback carrier synchronization)

这个文档对蓝牙开发有很大的帮助，希望可以帮到大家，(bluetooth)

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)
