Delay spread in Wimax

delay spread wimax

Hi


In Fixed Wimax if the 25% guard time and channel bandwidth is 3.5Mhz
The delay spread can be up to 16µsec.

How do we calculated this 16µsec?

sorry for trivial question but I am a new comer to this field

Added after 6 minutes:

OK

I get it
there was a missed figure, the no of sub channels = 256.

now it's clear

sorry for disturbance
