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.

How to convert SNR to EB no?

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.

What is bit error rate in wireless communication?

The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit error ratio is a unitless performance measure, often expressed as a percentage.
