Browning and its resoluble way in plant tissue culture 植物組織培養(yǎng)中的褐變現(xiàn)象及解決途徑
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u(píng)wb通信系統(tǒng)為背景,主要研究uwb系統(tǒng)室內(nèi)密集多徑信道的信道估計(jì)方法,以及基于turbo原則的迭代信道估計(jì)的接收機(jī)結(jié)構(gòu)。
