Energy-Optimised Coded Modulation for Short-Range Wireless Communications on Nakagami-m Fading Channels

When the distance between the transmitter and the receiver of a wireless communication link is sufficiently short, circuit energy consumption and transmission energy consumption become comparable, and substantial energy savings can be achieved by making use of a transmission scheme which takes into account total energy consumption instead of transmission energy alone. In this paper, we consider a trellis coded system operating on a Nakagami-m fading channel, and investigate the manner in which the trade-off between transmission energy and circuit energy consumption is affected by the value of the fading parameter m.
