前馈系统 meaning in English

feedforward system

Robust stabilization of a class of feedforward systems
一类前馈系统的鲁棒镇定
During the research , finding some important as follow : if wanting to get an ideal linearity of duamoop feedforward system , needing an accurate balance of amplitude and phase , so the attenuation , the delay and the phase in the circuit must be designed accurately
本项研究还发现，双环前馈系统要获得理想的线性化效果，还需要精确的幅度和相位平衡，这在电路的设计中表现为要对回路中的衰减和延迟以及移相环节进行准确的设计。
Vector modulators have been used in this paper to vary the phase and amplitude of signals in the in - band spurious cancellation loop of feed - forward power amplifiers ( ffpa ) . in the two - tone test , 3 . 5ghz ffpa developed in this paper shows more than 35db improvement in the third - order inter - modulation ( im3 ) , offers approximately - 60dbc im3 output , achieves the expected goal , and meets the communication requirement
本文研制的3 . 5ghz前馈放大器采用了矢量调制器来实现前馈环路的幅度和相位调节，在双音测试结果中，三阶交调im3的改善超过了35db ，前馈系统输出im3抑制近- 60dbc ，达到了预期指标，满足了通信需要。
