From: Morris Vian on 26 Feb 2010 14:35 Hi, I am using the "ricianchan" command to create my fading channel and then use the "filter" command to filter a baseband signal. However, I am left wondering if this setup will accurately model the Doppler frequency spread. Since the Doppler frequency spread is function of the carrier’s center frequency, would I need to first modulate my baseband signal to RF frequencies, pass it through the channel and then demodulate it to baseband again? Should I then use the same settings for the ricianchan command as I used for the baseband case? Is there a simpler way to include the carrier frequency into the model? Thank you so much for your help.
