Here is what I think. >Hi Everyone, > I would appreciate if someone can clear these points for me: > 1-problem 10.8, is spectral efficiency equivalent to bandwidth efficiency and not power efficiency? Spectral efficiency is bandwidth efficiency. > 2-10.20, I do not seem to get the meaning of "fade slope" in db/s. Are we supposed to get the fade as function of time and then get the slope or what? I think there is a number for fade/symbol and the symbol period is given; therefore you can calculate the "fade slope" in terms of db/s > 3- 10.24, are we required to figure out the cell coverage for AMPS and IS-54, I believe we haven't discussed those standards in the class. I think the question is only asking the difference among the systems, so you don't really need to know the specifics for those systems. > 4- I cannot seem to find a reference in the text book about the material we discussed in the last class (link budget). Is there any reference other than the class handouts. Don't know. > Thks > Amr Later. ..
