循环频率 meaning in English
cycle frequency
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。 - Ds signal is twice modulated with the rapid pseudorandom noise sequence and the carrier . so it appears cyclostationary . in the field of spectral correlation , ds signals appears its characteristic as fallows : for the amplitude of spectral correlation , the information of carrier frequency and pn code rate are contained on the spectrum frequency equal to zero sheet , and also the pn code rate is contained on the sheet of spectrum frequency equal to carrier frequency ; for the phase of spectral correlation , the information of carrier initial phase is contained on the sheet of cyclic frequency equal to double carrier frequency
Ds信号是经过高速伪随机序列和正弦载波二次调制的宽带信号,因此具有周期平稳特性,它在谱相关域表现为:幅频特性在谱频率等于零截面切片上包含了载频和伪码速率信息特征,在谱频率等于载频截面切片上包含了伪码速率信息特征;相频特性在循环频率等于两倍载频截面切片上包含了载波初相信息特征。 - 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。
