What is EB No and SNR?

Eb/N0 is equal to the SNR divided by the "gross" link spectral efficiency in (bit/s)/Hz, where the bits in this context are transmitted data bits, inclusive of error correction information and other protocol overhead. B = channel bandwidth, fb = channel data rate.

What does eb no stand for?

Eb/No is classically defined as the ratio of Energy per Bit (Eb) to the Spectral Noise. Density (No).

Why is EB N0 used instead of SNR?

Its main advantage is that the actual bandwidth is taken out of the equation, since N0 is simply the noise power in a 1 Hz bandwidth. This allows comparing different modulation schemes without having to worry about their spectral properties. EbN0=SNBRb.

How is EB number calculated from BER?

Eb/No = 77-10 log(10 Mbps) Eb/No = 7 dB Eq: (4.6) Calculation for Link Margin: Link Margin = Calculated Eb/No-Threshold Eb/No Link Margin = 7-10.5 dB Link Margin =-3.5 dB Eq: (4.7) Since link is negative and as per various standard like ESA, ECSS and NASA link margin should be in positive and > 3dB.
