frequency bias meaning in Chinese
频偏
Examples
- In research on de - multiplexing of cwtdm signals , the trouble resulted from frequency bias is studied in depth , thanking to which a synchronization module for de - cwtdm is advanced
针对cwtdm模块的关键问题一频偏对帧同步的影响，作了深入的理论分析和仿真，进而提出了实际系统的时分分接同步解决方法。 - In the traditional polarization diversity and combining scheme , differential mode loop and common mode loop is combined to lock in the phase and frequency of the diversity signals and remove the carrier frequency bias and doppler shift
传统的极化分集接收方案是将差模环和共模环相结合完成两路信号的同频同相锁定以及多普勒频率偏移的去除。 - And then the stability and the stable error response of the dpll are analyzed . there is an obvious doppler shift frequency offset in the received signal with flight at a high speed , in the dissertation the uniform sampling second - order dpll is used to remove the frequency bias for its excellent high - pass characteristic of the error transfer function
由于高速飞行的遥测目标在接收信号中会出现较大的多普勒频率分量,而典型均匀采样二阶数字锁相环dpll ( digitalphase - lockedloop )的误差函数具有高通特性,所以本文提出一种利用其高通特性来去除多普勒频率分量的新方法。 - Because of the structure of the traditional polarization diversity and combining scheme is too complex , after researching the polarization diversity and diversity combining technology , a new structure of receiver is proposed . in this structure the uniform sampling second - order dpll is used to remove the frequency bias after frequency discrimination
该结构控制较为复杂,为此结合实际项目要求,在研究了极化分集接收关键技术的基础上,提出了一种改进的极化分集接收机结构,即在鉴频之后利用均匀采样二阶数字锁相环误差传递函数的高通特性去除各种频偏分量。
