Hi Guys,
Just wondering if someone could help me out:
I have the following:
Eb/N0 uplink = 18.4dB
Eb/N0 downlink = 11.8dB
The formula that I am using is: (Eb/N0 uplink x Eb/N0 downlink) / (Eb/N0 uplink + Eb/N0 downlink)
I get 7.19dB
The answer is 10.9dB
I think my problem is that I have to convert dB to something, but I don't know how do I convert the dB so that I can use it in my equation?
Cheers,
