符号间干扰 meaning in Chinese
intersymbol interference
Examples
- Isi inter symbol interference
符号间干扰 - Secondly , we propose a multi - user detection based on kurtosis . this method can suppress not only mai ( multiple - access interference ) but also isi ( inter - symbol interference ) . all needs in the detection are only the desire user ' s spreading code
并在此基础上，提出了一种基于峭度的盲检测方法，这种方法不但可以抑制多址干扰mai ( multiple - accessinterference ) ，还可以抑制符号间干扰isi ( inter - symbolinterference ) ，而且在检测时只需要期望用户的扩频码信息，是一种全盲检测方法。 - For wireless communications , direct sequence code division multiple access ( ds - cdma ) techniques have received a great deal of attention due to the expectation of capacity increase , interference rejection capability , security , and so on . in a high data rate application such as multimedia services , however , the capacity of ds - cdma systems is limited by both the inter - chip , or inter - symbol interference
Cdma技术以其高抗干扰能力、高容量、高保密性等技术优势在第三代移动通信系统中被广泛应用，然而在高速数据业务中，严重的码间干扰和符号间干扰会导致系统性能明显下降。 - In order to achieve high data rates on the severely band - limited underwater acoustic ( uwa ) channels , bandwidth - efficient modulation techniques must be employed , together with some sophisticated signal processing algorithms , such as adaptive equalization technique for the intersymbol interference caused by channel multipath propagation
在带宽严重受限的水声信道中实现高数据率通信，必须使用高带宽利用率调制技术，并结合自适应均衡等技术以有效地克服信道多途传播产生的符号间干扰。 - For example , carrier frequency offsets , which are caused by the inherent instabilities of the transmitter and receiver carrier frequency oscillators , can lead to severe system degradation due to inter - carrier interference ( ici ) . symbol timing synchronization must also be achieved in order to avoid inter - symbol interference ( isi )
其载波频率误差会引入子信道之间的干扰( ici ) ，而帧同步的误差会引入符号间干扰( isi ) ，同时还会对信道估计带来严重的影响。
