An Energy-Efficient MAC Protocol for Mobile Ad hoc Networks

瑞利多径衰落信道仿真，jakes模型，有图(rayleigh fading)

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：  适用于VS2010以后的版本对串口进行读取数据和写入数据到串口。(Applicable to VS2010 and later versions to read data and write data to the serial port.)

说明：  NOMA系统级仿真，多用户，多径瑞利信道(NOMA System Level Simulation)

安卓手机调用蓝牙实现热敏打印机打印，多品牌打印机可用(Android mobile phone calls Bluetooth to print thermal printers, multi-brand printers are available)

。研究了瑞利衰落信道下两跳放大前传协作中继系统的最优化功率分配问题。推导了高信噪比条件下的协作中继系统的中断概率的理论公式. 协作中继 放大前传 最优化功率分配 误符号率 中断概率(Optimal power allocation for two hops amplify- and- forward cooperative relaying communication systems in Rayleigh fading channel was studied. cooperative relaying amplify-and-forward optimal power allocation symbol error rate outage probability)
