摘要
本文对一定条件下的有限长序列，依频谱模重建整个信号的问题提出了一种修正的松弛迭代算法，该算法充分利用了迭代过程中的前几次信息，并在算法不收敛的情况下采取人工扰动的方法，从而使算法收敛，计算机模拟结果表明，该算法收敛快，精度高，是一种行之有效的算法。
In this paper a modified relax iterative algorithm for reconstructing finite length signal from its mag-nitude is proposed. The algorithm uses the iteratiion information and the relax factor is modified when it does not converge the experimental results show that the algorithm has high resolution and convergence speed and is effec-tive.
