摘要

该序列估计器基于一组白化卡尔曼滤波器。它的计算复杂度大大降低，误差性能几乎与最大似然序列估计相同。由于同时存在衰落和ISI，误差概率仍然很低。为了提高误差性能，研究了分集传输。用计算机模拟了两种不同衰落信道模型的误差性能和计算复杂度。与分析预测的比较显示出良好的一致性。

Sequential sequence estimation of bandlimited signals over a frequency selective Rayleigh channel

The sequential sequence estimator is based on a set of whitening Kalman filters. It has considerably less computational complexity with an error performance almost identical to that of the maximum likelihood sequence estimation. Due to the presence of both fading and ISI, the error probability is still poor. To improve the error performance, diversity transmission is investigated. The error performance and computational complexity are simulated by computer for two different fading channel models. Comparisons with analytical predictions show good agreement.<>
