[edit]I could not understand this definition. Can someone explain it a bit more n a little better? What is it that you do not understand?
If the distance between the transmitter and the receiver is known, what can we say about the delay spread? —Preceding unsigned comment added by 12.53.113.242 (talk) 16:18, 15 January 2009 (UTC)
- If you only know the distance between Tx and Rx, you cannot say anything about delay spread. For instance:
- Let the distance between Tx and Rx in free space be 1 km. Since in free space there is no multipath, the delay spread is zero.
- Let the distance between Tx and Rx in a dense urban environment be 1 km. The delay spread in these environments can be, for instance, 1 us. Thus, the delay spread depends on the multipath richness of the environment. --Avalcarce (talk) 21:52, 11 September 2010 (UTC)
