摘要翻译：
提出了一种基于Blaschke解卷自适应傅立叶分解(AFD)的信号压缩算法。Blaschke解绕AFD是一种新的信号分解理论。该算法在每一分解步骤中都采用了Nevanlinna分解和最大选择原理，具有较快的收敛速度和较高的保真度。将所提出的压缩算法应用于心电图信号。为了评估所提出的压缩算法的性能，除了一般的评估标准之外，我们考虑了与临床需求相关的较少讨论的标准--为了心率变异性分析的目的，评估保留R峰信息的准确性。实验在MIT-BIH心律失常基准数据库上进行。结果表明，该算法的性能优于现有的其他算法。同时，它还很好地保留了R峰值信息。

英文摘要：
  This paper presents a novel signal compression algorithm based on the Blaschke unwinding adaptive Fourier decomposition (AFD). The Blaschke unwinding AFD is a newly developed signal decomposition theory. It utilizes the Nevanlinna factorization and the maximal selection principle in each decomposition step, and achieves a faster convergence rate with higher fidelity. The proposed compression algorithm is applied to the electrocardiogram signal. To assess the performance of the proposed compression algorithm, in addition to the generic assessment criteria, we consider the less discussed criteria related to the clinical needs -- for the heart rate variability analysis purpose, how accurate the R peak information is preserved is evaluated. The experiments are conducted on the MIT-BIH arrhythmia benchmark database. The results show that the proposed algorithm performs better than other state-of-the-art approaches. Meanwhile, it also well preserves the R peak information.
