Hello There,
I am trying to learn how to calculate power delay profile in a ray-tracing situation like this:
3-Dimensional room, Origin (0, 0, 0) at a corner.
room_dim = [ 2 3 2] ;
receiver_pos = [ 0 1 1 ] ; src_pos = [ 1 1 1 ] ;
(distance between the Tx and Rx is sqrt((1-0)**2 + (1-1)**2 + (1-1)**2 ) = 1m
Some additional parameters:
UWB frequency being considered (3.4 to 4.8GHz)
Pulse width 0.7
Sampling interval 0.08375 ns
Only upto 2nd reflection is considered.
c = speed of light.
assume all room walls are (perfectly) reflective.
I want to know (1) how long will it be (in ns) before the first (LOS) signal arrives. May be just divide the distance (1m) by 1e8, the speed of light.?
(2) How long will it be before the second ray is received by the antenna?
Please help me clarify this.
Thank you.
