REALIZATION OF RRO-NRDPWT-BASED ECG SIGNAL COMPRESSION WITH MODIFIED RUN-LENGTH CODING

摘要：

With high compression performance, realization of wavelet-based data compression system is significant for multi-lead ECG signal recording. In this paper, we proposed a modified run-length coding (MRLC) algorithm associated with an efficient quantization scheme for the realization of a RRO-NRDPWT-based ECG data compression system. The MRLC has the characteristics of regularity and low computational complexity which make it a suitable for hardware implementation at a cost of compression performance. This compromise will be compensated by the new quantization scheme. By using the MIT-BIH arrhythmia database, the experimental results show that the proposed scheme can be competitive comparing to other wavelet-based approaches in compression performance. In addition, the MRLC can improve traditional runlength coding by about 13％.
