Hello everyone,
I am trying to calculate the total trasmission time taken by signals to travel from a Transmitting end to a Receiving end through a Rayleigh/Rician fading channel.
According to me, i have thought of the below two solutions to proceed with this:
1) Considering the total time in terms of delay spread.
2) Finding the time difference of arrival, as mentioned in few research papers.
I would really appreciate any kind of input on this. Whether going by any of these solutions is the way, or is there a 3rd way to achieve this.
Thanks & Regards,
Rahul

Okay so i did my own research. And finally found the solution. Just so as to refer to, if anyone else get the same problem in future.
So to find the time difference, a good approach would be to use Saleh-Valenzuela (S-V) Channel Model. As it gives you time of arrival of each ray and cluster, to be assumed as delay in transmission and reception of signals.
Thank you
Rahul
