| 摘 要： | 文中提出一种基于概率软切换的两级双模盲均衡器。它实时统计两级盲均衡器输出硬判决值相同的概率,并利用它切换盲均衡算法。该均衡器结合了级联两级均衡结构和双模算法的优点。仿真表明,它能够纠正相位偏移,相对于波特间隔（BSE）的并发常模＋判决导引（CMA＋DD）盲均衡器,以非常小的计算复杂度代价,获得稳态均方误差（MSE）性能和误比特率（BER）性能的较大提高。 |

| Abstract: | A two-stage dual-mode blind equalizer with probability-based soft-switch is proposed in this paper.The equalizer computes the probability that the two equalizers output the same hard decision in real time,then to switch to proper blind equalization algorithm accordingly.Moreover,it combines the advantages of both cascaded two-stage structure and dual-mode algorithms.Simulations show that the proposed equalizer could correct phase offset and improve the performance of steady-state mean square error (MSE) and... |
