carrier signal to noise ratio

基本解释

As demodulator threshold of receiver decreasing, performances of traditional SNR (signal to noise ratio) estimation and carrier lock detection deteriorate greatly.
当接收机解调门限很低时，传统方法的信噪比估值和载波锁定判决性能都严重下降。
To the question of Carrier Synchronization with low signal-to-noise ratio (SNR) and High Dynamic , using the method of combining FLL with PLL to actualize the carrier tracking.
针对极低信噪比高动态条件下载波同步问题，采用锁频环（FLL）和锁相环（PLL）相结合的方法来实现载波跟踪。
Their main function is to simulate the satellite signal from the really satellite on the satellite orbit through changing code phase, Doppler shift, carrier and signal-to-noise ratio.
其主要功能就是通过改变码相位、多普勒频移、载波和信噪比来模拟卫星轨道上真实卫星发射的信号。
