说明：  浅析OPNET建模机制，适合初学者,里面讲解的很详细(Analysis of OPNET modeling mechanism, suitable for beginners)

说明：  杰理得蓝牙通讯程序，可用于蓝牙和FM音箱的开发。(Bluetooth Communicator)

一个新的通信协议，一线通协议模版软件，希望对大家开发有用(A new communication protocol, Link Agreement template software, everyone would like to develop useful)

雷达模糊函数仿真与信号处理。<br />radar ambiguity function simulation and signal processing .

用VB编写的串口调试助手，附带51程序，大家可以学习，很经典，很地道(With VB serial debugging assistant, with 51 programs)

实现信号处理中QAM调制、过信道、解调部分。其中QAM调制部分可改符号点数，M阶数，信道加高斯白噪声、时延、多径，调制解调均有星座图。通过本代码，可学习QAM调制解调，或者通信系统的知识。(To achieve QAM modulation, signal processing over channel, a demodulation section. QAM modulation section can be changed symbolic points M order channel additive white Gaussian noise, delay, multipath, the modem has constellation diagram. QAM modulation and demodulation, or communication system knowledge through this code, you can learn.)

说明：  ofdm 信道估计 16qam MMSE估计 对比了块状导频和梳状导频的区别(ofdm channel 16qam MMSE compare with block pilot and comb pilot)

说明：  提供了一个研究NOMA，如何NOMA解决了5G需求、NOMA正在进行的标准化工作以及NOMA与其他应用程序的比较研究像OFDMA这样的OMA方案。我们还展示了NOMA中用户吞吐量的改进在MATLAB仿真的帮助下实现OFDMA。(This paper provides a study of NOMA, how NOMA addresses the 5G requirements, ongoing standardization efforts for NOMA and a comparative study of NOMA with other OMA schemes like OFDMA. We have also demonstrated improvements in the throughput of the users in NOMA as compared to OFDMA with the help of MATLAB simulations.)

说明：  matlab里使用simulink仿真出qpsk系统通过AWGN信道的调制解调过程，并分析其误码率(Using simulink in matlab to simulate the modulation and demodulation process of qpsk system through AWGN channel and analyze its bit error rate)
