Dear Sir/Mam,

Hello, i am a student working on the development of a channel emulator,
Can

Regarding my last post i want to bring it to your notice that i have to
implement a multipath fading channel emulator so can you tell me how can
i

Hi Ritvik,

also notice that you might want to have a look at how things are done in

I think this block is just a single tap channel. If you want to have
multipath channel use channel_model2 instead:
