一种基于二次规划计算DFE系数的新方法
A Novel Method for Calculating the DFE Coefficients Based on Quadratic Programming
-
摘要: 判决反馈均衡器(DFE)是一种常见的均衡器类型，在实际中得到了广泛应用。对于采用最小均方误差(MMSE)准则设计的DFE，其系数计算一般利用正交原理推导获得。该文推导了一种新颖的基于二次规划方法计算MMSE准则下DFE系数的方法。仿真表明，该文所提方法与传统方法计算得到的结果是一致的，并且由于运用矩阵运算，在一定程度上简化了计算。Abstract: Decision Feedback Equalizer (DFE) is widely used in practice, which is usually designed according to Minimum Mean Square Error (MMSE) criterion. A novel method is derived for calculating the DFE coefficients based on quadratic programming. Simulations show that the new method is equal to the traditional one.
