摘要

本文采用率失真优化嵌入(RED)技术，从不同的心电信号中提取相对重要和不重要的比特，并采用不同率的低密度校验码(LDPC)对其进行保护，以实现不等错保护(UEP)性能。通过对比不同AWGN信道下的实验结果，观察重构信号的失真程度，来反映UEP性能。

Optimal rate-distortion based unequal error protection in the transmission electrocardiograph signal

In this paper, we are using rate-distortion optimized embedded (RED) technology to extract relatively more important and less important bits of different electrocardiograph (ECG) signals, which are protected by different rates of low-density parity-check (LDPC) codes to realize unequal error protected (UEP) performance. The UEP performance will be reflected by comparing experiment results that under different AWGN channel, then observing the distortion of reconstruction signal.
