提出了一种利用Legendre正交多项式简化Volterra级数模型的建模方法(Legendre Volterra Series,LVS).传统Volterra模型具有高精度和物理意义明确的优点,但其缺点在于计算量大,对硬件资源的消耗比较大,而且不利于对信号进行实时处理,该模型很大程度上减少了运算量,同时也保持了传统Volterra模型的优点.%In this paper, the volterra model for power amplifier based on Legendre orthogonal polynomial is improved. The conventional volterra model has the merit of explicit physical significance and high precision. But the model requires large amount of computation, and it is not suitable for real-time processing. The LVS model decreases the computation complexity a lot, and retains the advantages of the conventional one.
