Charan needs help for her book

[charan langton]

Hello everyone,

I am writing a comm book with Dr. Bernard Sklar and wish to get some help from EE/comm students. What I need is for you to solve the homework problems I will be creating and let me know if they are appropriately targeted, level of difficulty etc.

I will post the problems for each chapter on the website and would be most grateful if you would try to solve them and send me a PDF of your efforts.

If you want to read the chapters and critique, that is welcome too.

Thanks,

Charan Langton

We are very excited about your new book Charan!! Will immediately buy it once it is released and i'll highly recommend it to all my EE friends.
I'm not a student anymore and i've lost touch with my math capabilities but i'll definitely try solving them

Me, too! I can try although I am not a student any more.
Thank you Charan! I learned a lot from your tutorials. Thanks a lot! I appreciate it! Look forward to your new book!

Would be very interested in reading it!

I have just been through "Intuitive guide to Principles of Communications" and had some comments as follows- it was very informative, though!:
Page 3: Eb should have units of dBW, not dB because it's a power.
Example 2: It's not clear initially that it follows from example 1. Power units should be dBW.
Figure 2: It's got lost onto next page in my printout.
Page 6: Most dBs should be in dBW.
Page 6: I wondered what ES stood for; it is probably earth station.
Page 7: Example 4: I think dBw should be dBW.
page 15: Section "Computing Free Space Loss". I couldn't make sense of the numbers. If you express FSL in dB's, the constant term is 20log(4*pi/c) which comes to -147.6dBW for r in metres or -87.6dBW for r in kilometres.
page16: Ex6: Earth station at 22000km; per my calculations you should have FSL=-87.6+... resulting in Preceived=-72.5.
best,

Ed

Hi,

The hamming distance between 000110 and 001010 is 2 right? I found you said 3 in the coding file

[charan langton]

You are right. Numerous typos.

Ms. Langton,

I would like to proof read your new book.
By doing so I will be looking for:
1) Typos,
2) Incorrect statements,
3) Sentence structure more appropriate for an English speaking audience,
4) Rewording of ambiguous statements.

I assume as the forum administrator you have my email.
