摘　　要：阐述两种基于逆QR分解的RLS,并对两种算法进行了总结。新算法可以同步更新自相关平方根矩阵和自相关平方根逆矩阵,因此较传统算法权值提取更容易。采用systolic阵对两种算法进行硬件设计,分析表明第二种方法较传统的逆QRD-RLS算法实现复杂度更低,工作频率更高。This paper presents two kinds of inverse QR decomposition-based recursive least square(RLS) and sums up the achievement of these two algorithms.The novel algorithm extract weight easier than the traditional one,for which can update the square-root correlation matix and the inverse square-root correlation matix synchronously.Using systolic array algorithm for the two types of hardware design,the analysis shows that the second method,compared with the traditional IQRD-RLS algorithm,has lower complexity and higher operating frequency.
