time-delay spread

基本解释

Parallel factor analysis based space-time multiuser detection algorithm for CDMA systems with larger delay spread is presented.
空时多用户检测技术是一种有效消除CDMA系统中多址干扰和码间干扰的方法。
The wireless propagation environment is described first: analyzing the small-scaled fading, including amplitude fading, multi-path time delay and Doppler spectrum spread.
在本论文中，首先对移动传播环境作了描述，特别是对小尺度多径传播造成的幅度衰落，多径时延和多普勒频移进行了分析；
It is concluded that low altitude radio fuze channel is a doubly-spread channel, through which a signal propagates will experience both time delay and frequency spreading.
指出低空无线电引信信道是双展宽的时变信道，即引信接收到的地面回波是会同时产生距离扩展和频率扩展的双扩展信号。
