近十几年来，发展了一些相关的通信技术以最大的利用双选择性衰落信道的时间选择性和频率选择性.本文提出了一种新的基于训练序列的信道估计方法。
Coherent data communication over doubly-selective
channels requires that the channel response be known at the
receiver. Training-based schemes, which involve probing of the
channel with known signaling waveforms and processing of the
corresponding channel output to estimate the channel parameters,
are commonly employed to learn the channel response in
practice. (2010-06-15, PDF, 155KB, 下载13次)
