transmission path delay

基本解释

To build nationwide synchronized time net using SDH network, we must study the time delay in SDH network transmission path.
利用SDH网络组建全国的时间同步网，需要研究SDH网络传递路径的时延和时延误差。
For the problem of channel load-balance, information of links along a path is collected during the transmission of RREQ, and the final judge is based on link information and path delay both.
而对于信道负载均衡，通过RREQ消息在路由发现过程中对链路质量进行收集，采用了基于链路质量的判据并综合考虑了路径延时来进行路径选择。
OFDM is a high transmission technology in the wireless propagation environment. It is fitted to transmit high-speed data in the wireless channel which has multi-path delay and Doppler frequency shift.
OFDM是一种无线传播环境下的高速传输技术，适合在多径传播和多普勒频移的无线信道中传输高速数据。
