I/Q imbalance problem causes finite rejection in the image frequency band, and the image interference will alias into the desired signal, severe distortion will occur.
不平衡问题将会造成接收机的镜像干扰排斥能力大幅降低，镜像干扰将使得欲接收的信号严重失真。

In addition, the stop-bandrejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.
另外，在函数类型上使用椭圆函数型，使带外出现有限频率传输零点，进一步提高了带外抑制能力。

Adaptive filtering algorithms can be used on time domain to rejection Narrow-band interference (NBI) of man-made of enemy in DSSS.
