Presentation Media for Satellite Communication Systems

Hi everybody,

we are working on a new partition in our company based on satellite communication systems... and i'm working on making sessions to give ideas and main basics (or more) about it... my problem is with the presentation media... I don't have picturs (which is really important), educational movies, power point presentation, PDF, seminars, or anything to use in my sessions... so anyone plz have any usefull files, sites, links or what ever in this department?

also any thing of these subjucts can be usefull:

- DAMA
- SPADE
- ALOHA
- S-ALOHA
- FEC
- FED
- ARQ

thanks very much

I have the book satallite communication system by B.G. Evan which has some block diag. I could scan them in and post them to you.

However, they are not very attractive as they are mostly black and white.

this is exactly what i'm talking about! i have many books... but I need some attractive stuff as you said...
thank you very much...
