Different communication systems will have different curve of Eb/No vs. BER

Two ways to compare– vertical line and horizontal line:

1. horizontal line:

(for a given BER) some system needs less energy, which is good.

2. vertical line:

(for the same amount of Eb/No) some system provides less BER, which is good.

Furthermore, based on the graph, transmit power can be calculated.
