摘　　要：本文研究了对多径衰落信道的Ｖｏｌｔｅｒｒａ自适应预测。通过计算机模拟，分析比较了Ｖｏｌｔｅｒａ滤波器和一般线性横向滤波器的预测性能。结果表明，采用Ｖｏｌｔｅｒａ滤波器能够有效地提高预测的精度。同时，研究了信道预测在功率控制中的具体应用。The Volterra adaptive prediction of the multipath fading channel is studied in this paper.The performances of the Volterra filter and the conventional linear transverse filter are compared.The computer simulation results indicate that the Volterra filter can behave better than the linear transverse filter.As an example,the power control based on the channel prediction is analyzed.
