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))
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." rel="nofollow - Click Here for Next Tutorial
