Abstract

This letter presents a procedure of the capacity calculation for a multi-relay communication system for the assumed presence of additive white Gaussian noise and the flat fading in the channel. The exact formula for channel capacity as a function of channel parameters and the number of relays is derived. It was confirmed that the capacity of the network can be maintained and energy consumption can be reduced if the relay network is used.
