基于PR-QMF理论的判决反馈均衡器OA北大核心CSCD
PR-QMF based decision feedback equalization
根据完全重构正交镜像滤波器(PR-QMF)的理论,我们构造了一类正交变换并且用于变换域判决反馈均衡器(DFE)的设计。在此基础上我们进一步讨论了该类DFE的优化设计。通过与卡胡南—洛也夫变换(KLT)和离散余弦变换(DCT)比较得出这样的结论:经过最优化设计,本文提出的算法具有更快的收敛速度,同时,它还具有复杂程度低和设计灵活的优点。
Based on PR-QMF theory,we construct a class of orthogonaltransforms and apply them to the design of transform domain decision feedback equalization.Then we further investigate the optimization design of these DFEs.Compared with Karhunen-Loeve Transform(KLT)and Discrete Cosine Transform(DCT),we attain the following conclusions:the proposed scheme together with the optimization design can provide better convergence performance.In …查看全部>>
