Fig. 10From: Energy efficiency analysis of hybrid-ARQ relay-assisted schemes in LTE-based systemsEnergy efficiency versus transmit power in dBm for different EE computations. The HARQ-IR and HARQ-CC protocols are compared. Direct and cooperative transmissions are considered, and the adopted modulation is 16QAM. Dynamic power (DYN) related to the baseband processing is taken into account or not in the EE evaluationBack to article page
