Hi all,
I am working on the Ped. B channel model in WiMax system. However, I have some
problems about it. I hope that someone give me some clues or answers.
I am modeling the sounding SNR in WiMax system, and I use the channel model is
following: NLOS: ITU Modified Ped.-B, 3kmph, LOS: ITU Modified Ped.-B with K=
5dB, 3kmph. I have understood the model of LOS type that uses the Rician channel
in Matlab and how to connect channel with K factor. However, I don't know
how to build the NLOS type channel that is related to K factor. I think NLOS
should be constructed by Rayleigh channel, but, generally, Rayleigh channel
seems to be the special case of Rician when K=0. I have some troubles with
construction NLOS Ped. B channel model. I conclude my question as follow:
1. How can I construct a NLOS channel that is related to K
factor?(K=1,4,6,9,18)
2. I know that the K factor in the Rician channel is named Rician factor, but I
think NLOS is not suitable for this name because Rician channel cannot be used
in NLOS. And how can I call it? (I want to know this because I want to do more
searach and know more about its definition.)
3. There is few information about sounding SNR, could anyone provide me some
link or information about it?
Thanks a lot
Regards,
James
