Hi, I'm currently develop a DVB-S2 demodulator, and I want to know how to get the channel model (written in matlab or c etc.). I've been told that the standart organization (i.e., ETSI on my case) may supply something like that, but unfortunatley I've could not find it. Please help me! :) Moshe.

Generally DVB-S mass-production receivers are for VSATs with directional antennas, are stationary and of fixed alignment - pointing roughly at the satellite. If this is the case then an AWGN channel model is often adequate. Best of Luck - Mike

I thought that maybe there are some nonlinear phenomena associtated with this channel. Moshe

how about ETSI-UMTS CHANNEL MODEL. which is for man. does it fit in your scenario, check that bcoz one guy who was working in this field worked on some channel models in his simulation.....

From what I've seen the ETSI UMTS channel model is a model for mobile communication channels. Dont you think that it may be a too complicated model? I think that the sattelite channel is much simpler. Anyway, is there a matlab code available for this channel model? How can I get it? (I really dont want to waste time on building it myself).
