Efficient VLSI Architecture for ECG Data Compression

This paper presents an efficient ECG signals compression techniques using a 2D DWT coefficient thresholding and its design implementation of an efficient JPEG2000 encoder that employs the Distributed Arithmetic (DA) technique for the complex computation of Discrete Wavelet Transform (DWT).2D approaches exploit the fact that redundancy of ECG signal occurs between adjacent beats and adjacent sam...

Efficient VLSI Architecture for Lossless Data Compression

An architecture for LZ1-type lossless data compression is described. The architecture is area-efficient and fast since it exploits the locality of substring match lengths. The property has been shown experimentally for various data and buffer lengths, and an architecture based on it has been designed.

ECG Compression by Efficient Coding

Electrocardiogram (ECG) data compression algorithm is needed to reduce the amount of data to be transmitted, stored and analyzed, without losing the clinical information content. This work investigates a set of ECG data compression schemes to compare their performances in compressing ECG signals. These schemes are based on transform methods such as discrete cosine transform (DCT), fast fourier ...

ECG Compression by Efficient Coding

The continuous demand for high performance and low cost electrocardiogram (ECG) processing systems have required the elaboration of more and more efficient and reliable ECG compression techniques. Such techniques face a tradeoff between compression ratio and retrieved quality, where the decrease of the last can compromise the subsequent use of the signal for clinical purposes [1]. The objective...

Efficient Data Compression of Ecg Signal Using Discrete Wavelet Transform

Abstract Data compression reduces the number of bits of information required to store or transmit the biomedical signals. Compression algorithm of bio-medical signals is implemented using Discrete Wavelet Transform. High threshold value (λ) gives high data reduction and poor signal fidelity and low threshold value (λ) gives low data reduction and high signal fidelity. Threshold value selection ...
