这里提出一种自适应的减除重影系统。这个系统由一个重影减除滤波器和一个重影再生滤波器串联构成。为了满足这两个滤波器的传递函数的相互关系，自适应处理迫使本系统的输出曲线与输入曲线保持相同。该系统功能犹如一个封闭的叠合系统。
Here an adaptive subtraction ghosting system is proposed. This system consists of a ghost subtraction filter and a ghost regenerative filter in series. In order to satisfy the correlation between the transfer functions of the two filters, adaptive processing forces the output curve of the system to remain the same as the input curve. The system functions like a closed overlap system.
