But the finite propagation delay between the MS and BScauses a mismatch. Therefore, the clock at the MS would have to beadvanced by the finite propagation delay time, in order to maintainsynchronism. Implementing this would introduce undue complexity. Instead,we work a way around this problem by setting thepropagation delay to zero (in <I> ns</I>/wirelessphy.cc).<P><BR> <HR><P><ADDRESS><I>Richa Jain (96D07007) <BR>Tue Jul 24 22:29:53 IST 2001</I></ADDRESS></BODY></HTML>⌨️ 快捷键说明
