Eb/No Calculation

   Eb/No Calculation

Eb/No is the Energy per bit divided by the spectral noise density. 

Eb/No is related to the C/No.

Eb/No = C/No - (10 x Log(data rate))

Example:

If the data rate is 2048 kbps or 2 Mb then Log(2048000) = approx 6.31

If the C/No is 65 dBc/Hz then 

Eb/No = 65 - (10 x 6.31) = 65 - 63.1 = 1.9

Usually an Eb/No of at least 6 or more is expected so in this example the C/No is too small.
