Abstract
This article presents a surface electromyography signal compression algorithm based on wavelet transform and sub-band adaptive bit allocation. The proposal is an allocation profile that fits a logarithmic curve according to the energy o f each sub-band. The results obtained, compared to others previous works found in literature, outperforms those in a wide range of objective evaluation metricsDownload
