- Abstract:
- This paper introduces a new encoding algorithm for the lossless, fast, and memory-efficient compression of two-channel signals. The proposed algorithm was evaluated using Electrocardiogram (ECG) signals. The results indicate that it can effectively compress ECG signals with a favorable compression ratio (CR), without relying on complex predictors, dictionaries, detectors, or additional encoding methods. By employing this method, an average CR of 1.98 was achieved, with a minimum CR of 1.54 and a maximum CR of 2.36. Moreover, it is assumed that the algorithm has the potential to enhance the achieved compression in Compressed Sensing (CS) systems.
