systolic algorithm 中文意思是什麼
-
The improved algorithm not only inherits the fast convergence trait from rls and realizable systolic array from qr _ rls, but also eliminates square - root operation and gets directly equalizer output signals from systolic array. so this algorithm has more simple operation, faster executing speed, less hardware resource and lower hardware cost. some different equalization algorithm are imitated on the qpsk communication system with multipath channel
其次對一些成熟的自適應均衡演算法（如lms演算法、 rls演算法、 qr _ rls演算法、逆qr _ rls演算法）進行了分析;介紹了一種改進后的無平方根的qr _ rls演算法，該演算法不但繼承了rls的快速收斂特性和qr _ rls演算法的systolic陣列可實現性，還取消了qr _ rls演算法的平方根運算，使演算法在硬體實現時運行速度更快，佔用資源也更少，同時該演算法還可由systolic陣列直接得到均衡后的輸出信號，運算量更小。 -
Since the filtering vector is needed in qrd - rls and qrd - brls, the parallelism of qr decomposing will be impeded slightly. the inverse qr decomposion ( iqrd ) scheme for brls algorithm is proposed in this dissertation to enhance the parallelism, the systolic array structure for iqrd is proposed to calculate the algorithm in parallel
鑒于碼輔助最優濾波需要求解濾波權值矢量，此時qr分解的計算并行性不如逆正交三角分解（ iqrd ） ，本文提出了基於iqr分解的brls演算法，給出了iqrd - rls / brls的脈動陣列并行計算結構。
