Browning and its resoluble way in plant tissue culture 植物组织培养中的褐变现象及解决途径
2.
In order to utilize the resoluble ability of signals and improve resistant ability to multipath fading , the rake receiver is a good option . but proper rake operation requires information about the delays and attenuations of the channel paths which is difficult to obtain 本文以uwb通信系统为背景,主要研究uwb系统室内密集多径信道的信道估计方法,以及基于turbo原则的迭代信道估计的接收机结构。
