邻道干扰 meaning in Chinese

monkey chatter; adjacent channel interference

The predistortion , which aims at compensating for the nonlinear distortion caused by the power amplifier , has a good performance in eliminating the nonlinear distortion of am / am & am / pm , improving the aci and spectrum efficiency
预失真技术是针对射频功率放大器非线性而提出的一种补偿技术，可以有效消除由非线性造成的传输信号的幅度和相位失真，降低信号邻道干扰( aci ) ，提高频谱利用效率。
Since the envelope of modulated signal fluctuates , these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ) . so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci )
但包络变化的调制信号经过非线性射频功放后会产生交调分量，因此必须采用线性化技术来减少由此产生的邻道干扰。
