说明：  车载设备写码说明 关于现在的CDMA改ENS码的资料~真的很有用的呀！你可以自己解决这个问题！(On-board equipment to write code on the current CDMA to ENS code data ~ really useful ah! You can solve this by yourself!)

说明：  用Q-Learning实现中继选择，选择最佳中继进行通信传输(Realization of Relay Selection with Q-Learning)

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)

给出了OFDM在卫星通信中的系统框图并 在Simulink中仿真实现，利用改进的CMA恒模算法进行盲均衡处理，来去除时变卫星信道对信号的影响,基于4阶累积量的方法 将OFDM信号与其他调制类型信号区分开来(OFDM is given in the satellite communication system block diagram and Simulation in Simulink using the modified constant modulus algorithm CMA for blind equalization, to remove the time-varying satellite channel on the signals, based on 4-order cumulant method OFDM signals and other types of signal modulation to distinguish)

说明：  多径信道的生成函数 ，瑞利多径衰落信道生成。(Multipath channel generate. This function generates a uncorrelated multipath Rayleigh fading matrix.)
