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。
This paper describes the QAM, FSE and three least squares algorithms for high-speed data transmission over voice-band telephone lines: Kalman, Fast Kalman, and Adaptive The adaptive lattice algorithm is used to adjust the coefficients of the above system. Finally, a brief introduction to the method of realization.
