摘要
新的嵌入零树小波ECG信号编码算法能够通过合理分配比特、改进零树集合、完善分类策略等措施进一步提高SPIHT算法的工作效率 .实验结果表明 :这种算法是一种高效的ECG信号编码算法 ,其压缩速度、信号复原质量等关键性技术指标均明显优于SPIHT算法 .
In this paper, a new embedded zero tree wavelet ECG signal coding algorithm is presented, in which the bit allocation is changed, the zero tree set is improved and the partition-sorting strategy is revised. The experimental results show that our proposed coding method performs better than that of SPIHT I the aspects of PRD, encoding time and decoding time.
