我们提出了一种盲信号分离算法(CLUE),它使用提取的信号的各个码长的总和作为分离性能的衡量标准。新技术结合了广泛使用的通用数据压缩程序与任何单参数搜索程序。与以前的方法不同,该方法是无模型的,不依赖于其分离性能的信号的矩值。一个例子表明,该算法的有效性分离的图像,音频和文本数据的混合。
We propose a blind signal separation algorithm (CLUE) that uses the sum of the individual code lengths of the extracted signals as a measure of the separation performance. The new technique combines a widely-available universal data compression routine with any single-parameter search procedure. Unlike previous approaches, the proposed method is model-free and does not rely on the moment values of the signals for its separation performance. An example shows the algorithm's efficiency in separating mixtures of image, audio, and text data.
