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. -
