Data rate calculation
I want to know the relation between data rate & bandwidth for QAM, Coherent and non coherent PSK, FSK.
Thank you

Re: Data rate calculation
I am not very sure about this but as far as I know,
if ur using a 16QAM => 16= 2^4 so 4 bits per symbol. and ur symbol rate = baud rate.
If N bits are conveyed per symbol, and the raw bit rate is R(data+ channel coding bits) the symbol rate can be calculated as:
f_s = R / N.
I dont know about PSK. look into Communication System by Simon Haykins

Data rate calculation (data rate vs. bandwidth for QAM)
I have posted a problem in my blog ( http://gaussianwaves.blogspot.com )on Bandwidth calculation from Data rate for Mary PAM .
You can find similar equation for QAM, Coherent and non coherent PSK, FSK in digital communications by John G. Proakis
