该模型由一个无记忆非线性元件后接一个线性时滞环节组成，是描述非线性系统的一种基本模型形式。

The Hammerstein model, which consists of a zero-memory non-linear element followed by a linear time-delayed plant, is one of the basic models that describe a non-linear characteristic.

因此，无记忆预失真器不能校正放大器的记忆非线性失真。

So tranditional memoryless predistortion can not compensate memory nonlinear distortion of PA.
