This dissertation focuses on the carrier recovery in high dynamic navigation receiver , the effect of iq mismatch in direct down conversion receiver and the signal to noise ratio estimator in navigation receiver
本文以二代卫星导航定位系统为应用背景,着重研究了接收机中的载波恢复技术、 iq非正交对伪码和载波影响的模型、载噪比估计技术。
In order to monitor the satellite , carrier to noise ratio estimator is needed in receiver . the widely used carrier to noise ratio estimator is sensitive to residual doppler frequency . we present a new estimator whose property is somewhat better than the widely used one
以上的研究均以实际应用需求为出发点,充分考虑了实际实现中的可能会遇到的问题,其中载噪比估计及载波跟踪技术已成功地应用到某国防重点型号的接收机中。
