ADAPTIVE EQUALIZAT1ON FOR HIGH SPEED DATA TRANSMISSION OVER VOICEBAND TELEPHONE LINES
-
摘要: 本文沦述用于话音频带电话线路高速数据传输的正交调幅系统(QAM),分数间隔均衡器(FSE)和三种最小二乘算法:卡尔曼(Kalman)算法、快速卡尔曼算法和自适应网格式(adaptive lattice)算法用于上述系统的系数更新调整。最后简要介绍实现的方法。

Abstract: Quadrature-Amplitude Modulated (QAM) systems, Fractionally-Spaced Equalizer (FSE) that are for high speed data transmission over voice-band telephone lines are presented. The Kalman, fast Kalman, and adaptive lattice algorithms using a least square cost function to above systems are discussed. The paper concludes with the section about implementation approaches. -
