| 摘 要： | 文章提出了盲均衡的一种快速算法。该算法基于将通信信道建模成IIR信道，并在信道输出端过采样将信道转化成具有相同系数的AR子系统和SIMOFIR子信道的级联，通过对AR子系统和SIMOFIR子信道分别均衡实现IIR信道的盲均衡。仿真实验表明，在约25dB信噪比时，算法只需要少量的样本点即可快速收敛。

| Abstract: | In this paper, we present a fast algorithm for blind equalization. The communication channel was modeled as an IIR channel and the output of the channel was oversampled, so the channel can be seen as a concatenate of an AR sub-system with the same coefficients and a SIMO FIR sub-system. The blind equalization of IIR channel was implemented by equalizing the AR sub-system and SIMO FIR sub-system independently. The numerical experimentation demonstrates that the algorithm can be converged when there are short data and the SNR is 25 dB. |
