Spectral efficiency (SE), energy efficiency (EE), and transmission reliability are basic
parameters to measure the performance of a cellular network. In this paper, spectral
efficiency and energy efficiency tradeoff is considered keeping in mind the transmission
reliability, where all the three are function of signal to noise ratio (SNR). SNR, in turn is a
function of constellation size (or the number of bits per symbol) and data rate. Then, we
propose a new power model which is as function of this SNR. Based on the power model,
SE-EE trade-off function is evaluated taking transmission reliability in to consideration.
Results confirmed that increasing constellation size results an increase in SNR and leads to a
significant increase in energy efficiency without changing the transmit power. To
demonstrate the validity of our analysis, channel gain and constellation size are varied
keeping transmit power constant. The results also indicate that securing transmission
reliability, the EE-SE trade-off is optimized by increasing the constellation size.
