摘要
本文利用Teoeplitz矩阵和正弦变换基预条件矩阵的性质,结合预条件共轭梯度法(PCGM),对非均匀采样信号提出了一种新的重构方法,该方法针对文献[1]所构造的模型,在不增加运算量的前提下,扩展了原算法的适用空间,提高了信号重构的效率。
By making use of the properties of Toeplitz matrix and sine-based preconditioned, a new reconstruction algorithm for non-uniform sampling signals based on the preconditioner conjugate gradient method is put forward. Under the model in reference [3] , the new algorithm extends the application space and improves the reconstruction efficiency.
