Because methods mentioned above are sensitive to the error of the cyclic autocorrelation function estimation, a new method is proposed further, in which the order of the channel is estimated, and then a channel is achieved by estimating its zeros.
由于基于求解线性方程组的算法对接收信号周期自相关函数估计误差很敏感，本文进一步提出一种新的算法，首先进行信道阶数的估计，然后通过估计信道零点间接获得信道估计值。
