Energy efficiency comparison with zero circuit power and symmetric bidirectional packet sizes. Energy efficiency comparison with zero circuit power and symmetric bidirectional packet sizes. The curves of DT and OWRT with α = 4 respectively stop at (B ab + B ba )/(TW) = 4.4 and 4 bit/s/Hz, since larger packet sizes will result in unacceptable outage probability as shown in Figure 4.
