But if above positive real condition is satisfied only within some frequency range, the convergence of FXLMS algorithm is dependent on the spreading of power spectral density of the reference signal.
若上述正实条件仅在某些频带上满足，则FXLMS算法的收敛将依赖于参考信号功率谱密度的分布。

A method of minimum weight design with the lowest frequency as the constraint frequency is provided, and the iterative formulas and convergence criteria are found.
构造了一种以结构最低固有频率作为约束频率的结构最轻重量设计方法，并建立了相应的迭代公式和收敛准则。

The simulated result demonstrates that this method have the same convergence performance and misadjustment as the traditional ALE. The approving frequency spectrum estimation result was obtained.
