The header "EbN0" represents the ratio between the average energy used to transmit a bit and the noise power spectral density.
The header "BER" represents the bit error ratio.
Each column labelled as BER is plotted as a curve in the figures of the paper, corresponding to one of the set of scheme, namely the set of (628.3, 0.01), (718.8, 0.01), (718.8, 0.1), (1217.3, 0.1) and (1217.3, 0.3) for using 90nm fabrication technology and the set of (760.0, 0.01),
(869.5, 0.1), (1171.2, 0.1), (1472.8, 0.1) and (1472.8, 0.3) for using 45nm fabrication technology.
The order of the BER columns follows the same order as stated above.
