摘要

本文提出了一种利用给定旋转的广义决策反馈均衡器(GDFE) QR分解核。给定旋转由相位提取、正弦/余弦生成和角度旋转三个部分组成。结合定宽修正布斯乘法器和粗、细两阶段法，设计了一种高效的QR分解核心。仿真结果表明，所提出的QR分解核是一种可行的GDFE解。

Hardware Efficient QR Decomposition for GDFE

This paper presents a QR decomposition core by exploiting Givens rotation for the generalized decision feedback equalizer (GDFE). A Givens rotation consists of phase extraction, sine/cosine generation and angle rotation parts. Combining the fixed-width modified-Booth multiplier and two-stage method (coarse and fine stage), we design an efficient QR decomposition core. By simulations, it is shown that the proposed QR decomposition core can be a feasible solution for GDFE.
