LDPC性能仿真(LDPC performance simulation)

说明：  UR旋转矢量转化，转化为RPY坐标，更加适合编程，非常靠谱(UR Rotation Vector Conversion)

WINDOWS 应用程序（嵌入web浏览器），通过IC/NFC读卡器读取卡号,(IC/NFC card reader,can recognize card sn.)

WSN中节点确定性部署算法代码，覆盖率达到100％，算法思路简单，易于实现(Uncertainty in the deployment of WSN node algorithm code, the coverage reached 100, algorithm idea is simple, easy to realize)

说明：  经典无线链路预算模型，预测了在自由空间中由地形的非规则性造成的中值传输衰落。该模型适用于频段为20MHz至40GHz、路径长度为1km至2000km的情况。对于给定的传输路径，该计算机程序通过频率、路径长度、极化方向、天线高度、表面绕射率、地面有效半径和地面导电常数等参数可以确定传输损耗的大小。(Classic wireless link budget model, forecasts the in free space caused by terrain of regularity in the value decline.The model is suitable for the frequency of 20 MHZ to 40 GHZ, path length of 1 km to 2000 km.For a given transmission path, this a computer program can calculate the value of the transmission loss by frequency, path length, polarization direction, antenna height, surface diffraction, effective radius of the ground and ground conductivity constant parameters and so on.)

S60官方视屏播放器程序，可以装到手机上运行，但是在模拟器上运行会出问题。据说是因为视屏播放服务器的内核有问题，不能在模拟器上用。本人手机上测试成功。(S60 official video player program can be installed to run on mobile phones, but will run in the simulator problems. It is said that is because the screen play of the core server has problems, should not use the simulator. I test the success of mobile phones.)

估计接收到的直扩信号的载频，码速率，以及扩频增益(Estimate the carrier frequency, code rate, and spread spectrum gain of the received DSS signals)

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

说明：  用于通信方向中的信道估计，使用的语言是matlab(Used for channel estimation in the communication direction, the language used is matlab)
