提出了一种应用于Loran-C天波时延估计的稀疏降噪方法，该方法简单实用。利用信号稀疏性来减少罗兰频带内的噪声，并显着提高估计性能。由于计算过程中没有矩阵求逆，所提出的方法显示出更高的估计精度和更低的计算复杂度。
A sparse noise reduction method applied to Loran-C skywave delay estimation is presented, which is both simple and practicable. Signal sparsity is utilised to reduce the noise inside the Loran frequency band and significant improvement in the performance of estimation is achieved. The proposed method shows increased estimation accuracy with reduced computational complexity owing to no matrix inversion in the computation process.
