| 摘要: |
| 在具有码间干扰的多入多出（MIMO）无线通讯系统中，针对酉空时编码，提出了一种新的分数间隔矩阵恒模盲均衡算法。这种新算法比矩阵恒模算法表现出更快的收敛速度、更好地抑制噪声的性能。这种均衡器可以和非相干检测器配合使用．从而存存在码间干扰的情况下实现低复杂度的完全盲均衡。 |

| Abstract: |
| A new blind equalization algorithm based on unitary space-time code for Multiple-Input-Multiple-Output(MIMO)wireless communication system in presence of intersymbol interference(ISI)is proposed. This new algorithm has better converge and interference suppressors performance than what Matrix CMA algorithm has. This blind equalization algorithm can work with a noncoherent decoder, resulting in a low-complexity and completely blind method for decoding in the present of ISI. |
