正交镜像滤波器组是多抽率数字信号处理领域研究的问题。

Quadrature mirror filter Banks is a project which belongs to multi-sample rate digital signal process.

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。

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.

然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。

Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.
