cyclic correlation meaning in Chinese

循环相关

In this paper , a variety of familiar signals and channels are firstly analyzed and then the methods of dft and cyclic correlation are introduced
本文在分析各种常见的通信信号和信道的基础上，采用了离散傅立叶变换和循环相关方法解决信号载频偏差的高精度估计问题。
Dft method can be fast implemented on dsp platform by the use of fft algorithm , while the method of cyclic correlation has better noise immunity performance and high estimation accuracy
离散傅立叶变换方法能够在dsp平台上通过fft快速实现，而循环相关方法则具有很高的频率估计精度和很好的抗噪性能。
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。
