  5. Among the adaptive beam - forming algorithms, the least mean square algorithm is widely used because it has a simple configuration and it is apt to come true and have nice convergence. on the other hand, it has a disadvantage that it converges slowly and there is a conflict between the fixed step and the convergence pace or the error in stabilization. so people have developed many improved least mean square algorithms which generally start from convergence, stabilization, misadjustment, and robustness and come to a formula about variational step in the end

    在自適應波束形成演算法中,最小均方( lms )演算法因結構簡單,易於實現,能穩定收斂而得到廣泛應用,但它也存在收斂速度受限的缺點:固定步長因子無法解決收斂速度和穩態誤差之間的矛盾。因此,人們提出了各種改進的最小均法演算法來解決這一問題。改進的最小均方演算法通常從如何改進收斂速度、穩態誤差、失調量和魯棒性等指標上出發,最後在新演算法最終表達式中的步長公式上變化。
