The orthogonality, however, is impaired by multipath fading channels, thus causing multicode interference (MCI) and deteriorating the system's performance at high data transmission rates.
但是这种正交性却被多径衰落信道破坏，产生了多码道干扰，严重影响了系统高速传输数据的性能。
For UWB is mostly applied in dense multipath indoor circumstance the study on Inter Code Interference (ICI) caused by multipath is very importance for designing a high rate UWB system.
由于UWB主要应用在密集多径的室内环境，所以研究多径效应造成的码间干扰对于设计高速uwb系统非常重要。
It can waken the multipath effect availably, eliminate symbol interference and fight against frequency select fading. Moreover, the channel utilization rate is high.
他能有效地对抗多径效应，消除符号间干扰，对抗频率选择性衰落，而且信道利用率高。
