GMSK
- GMSK是高斯滤波的最小频移键控的简称,基本的工作原理是将基带信号先经过高斯滤波器成形,再进行最小频移键控(MSK)调制。由于成形后的高斯脉冲包络无陡峭边沿,亦无拐点,因此频谱特性优于MSK信号的频谱特性。-GMSK Gaussian filter is the smallest FSK abbreviation, the basic working principle is to base-band signal to pass Gaussian filter shape, and then

MATLAB
- 由于多径效应和移动台运动等影响因素,使得移动信道对传输信号在时间、频率和角度上造成了色散,即时间色散、频率色散、角度色散等等,因此多径信道的特性对通信质量有着重要的影响,而多径信道的包络统计特性则是我们研究的焦点。根据不同无线环境,接收信号包络一般服从几种典型分布,如瑞利分布、莱斯分布等。在此专门针对服从瑞利分布的多径信道进行模拟仿真,进一步加深对多径信道特性的了解。-Due to multipath effects and the mobile station sports and other
