    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 16-QAM => 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 M-ary PAM .
    You can find similar equation for QAM, Coherent and non coherent PSK, FSK in digital communications by John G. Proakis
