摘要
讨论了离散多频音 (DMT)调制系统中信道时域均衡器的训练算法 ,通过采用频域刷新及时域窗技术 ,使均衡后的信道响应均方误差最小 。
In discrete multitone (DMT) modulation system, a channel time domain equalizer training algorithm is studied. The adaptation in frequency domain and windowing in time domain are adopted to minimize mean squared error of the equalizer responses. Simulation results for the training algorithm of time domain equalizer are given.
