| 摘 要： | 以单片机为主控器件的HOLTER(动态心电监护仪)系统的实时性和临床诊断的保真度要求都较高,这就要求使用于其上的压缩算法应简单高效且近无损,而目前针对此类设备的压缩算法虽然有较高的压缩率,但失真度和复杂度也较高。本文提出一种针对HOLTER系统的低复杂近无损预测算法,实验表明,该方法在保证一定压缩率的条件下,具有很好的实时性和保真度。

| Abstract: | Systematic HOLTER real-time and the clinical diagnosis fidelity taking Single-chip machine as main controller demand all comparatively highly,this request use in the above compression algorithm should highly effective and near lossless,but aims at this kind of equipment's compression algorithm at present,although has the high compression ratio,but Distortion degree and complicated degree are also higher,In view of HOLTER system,this paper proposes one kind of low complex and near lossless predictor algorith... |
