1. The design of STC is based on frequency nonselective fading channels. For frequency selective fading channels, how to use STC is a problem deserving to research. 空时码是基于频率非选择性衰落信道设计的,对于频率选择性衰落,如何利用空时编码技术是一个非常值得探讨的问题。
2. Beauteous white roses are blooming peacefully in the wizard's secret garden. Someone could hear the voice of blooming whilst someone might see the sequel of fading. 巫师安静的后花园美丽的白色玫瑰就那样安静的绽开有人能听到她开花的声音有人也能看到花落的结局…
3. Simulation results show an evident improvement in AWGN and correlated Rayleigh fading channels. The severe intersymbol interference (ISI) of GMSK signals is also effectively suppressed. 仿真结果表明,在AWGN(加性高斯白噪声)和相关瑞利衰落信道下,系统性能均有显著改进,并能有效克服GMSK信号所固有的严重符号间串扰(ISI)。
4. But today Humber Coastguards said the canoeist and his craft were still missing and hopes were fading. 今天汉伯海上警卫队说找到失踪者和他的独木舟的希望越来越渺茫。
5. Chamberlain said he was hoping to return in time to have an impact on a Yankees team that is fading. 乔巴说,他希望自已能够及时归队,带给季后赛希望渐渐渺茫的洋基一些正面的能量。
