Abstract

In this paper we analyze the cutoff rate of a single-hop communication system taking into account the energy of the transmitter and receiver. An approximate formula is derived for the rate that achieves minimum energy consumption. We also present numerical results for Reed-Solomon(RS) codes over the AWGN channel. The results show that as the contribution of processing power increases, the optimal code rate to achieve the minimum energy consumption increases. Beside the AWGN channel, we also analyze the cutoff rate over a Rayleigh flat fading channel using the cutoff rate for binary frequency shift keying with noncoherent detection.
