Abstract :
We study power dissipation in relay-assisted wireless transmissions. Two types of assistance are considered: simple relaying and regenerative repeater. We find minimum transmit power levels to provision the same bit error rate in both cases. The simple-relay case considers power adjustment for error propagation at the intermediate relay node. Power consumption comparisons are made and results are discussed.
