freq. error frequency error
frequency error
Examples
- Especially forgetting factor ecab has excellent performance under large cyclic frequency error
特别是遗忘因子ecab算法，在循环频率误差较大的情况下，仍能保持很好的性能。 - Furthermore , a new time and phase synchronization scheme using a globe positioning system of a satellite ( gps ) is presented
该方案克服了传统时间同步装置需要较长时间来校正频率误差的缺陷，使校正后的精度大为提高。 - Cycle frequency - based blind beamforming shows the performance degradation due to cfe ( cyclic frequency error ) . an improved algorithm is presented in literature 6 , which adopting forgetting factor in estimation cyclic correlation matrix would largely depress the sensitivity of cab to cyclic frequency error . by using this method , the improved algorithms of the c - cab and ecab algorithms are presented in this dissertation
针对基于循环频率的盲波束形成算法对循环频率误差cfe ( cyclicfrequencyerror )很敏感而导致算法性能下降的情况，参照文献[ 6 ]提出的遗忘因子cab算法，提出了c - cab算法以及基于特征空间的盲波束形成算法( ecab )的改进算法。 - For example , carrier frequency offsets , which are caused by the inherent instabilities of the transmitter and receiver carrier frequency oscillators , can lead to severe system degradation due to inter - carrier interference ( ici ) . symbol timing synchronization must also be achieved in order to avoid inter - symbol interference ( isi )
其载波频率误差会引入子信道之间的干扰( ici ) ，而帧同步的误差会引入符号间干扰( isi ) ，同时还会对信道估计带来严重的影响。 - And typical super heterodyne structure in rereiver part . this scheme benefited to reduce frequency error and phase error , and had the advantages of good dynamic range and selectivity , short exploitation cycle and small venture in the given performance demand , etc . this system implemented a six - layer hoard rf handset model together with baseband by using advanced eda tool veribest 2000
