| 摘 要： | 本文首先分析最大缩短信噪比(MSSNR)算法的原理,然后证实基于该算法的时域均衡器有对称性的特性,并通过仿真验证。最后提出改进算法,即对称的最大缩短信噪比算法,该算法能有效强化均衡器的对称性,使运算量大大减少,复杂度降低。

| Abstract: | The theory of maximizing shortening SNR algorithm is introduced ,then the property that the time-domain equalizers based on the algorithm are often nearly symmetric is demonstrated and proved by simulation. Fanally, an improved algorithm called symmetric maximum shortening SNR algorithm is proposed which can enforce the symmetry of time-domain equalizers and greatly reduce the design and implementation complexity. |
