Optimal Power Allocation for Non-Regenerative Multicarrier Relay-Assisted PLC Systems with QoS Constraints
In this paper we present an iterative algorithm to jointly optimize the source and relay power allocations for a general relay transmission system, i.e. the broadcast-and-multi-access multicarrier relay system, where the source transmits in two time-slots. Under (but not limited to) the indoor power...

| description | In this paper we present an iterative algorithm to jointly optimize the source and relay power allocations for a general relay transmission system, i.e. the broadcast-and-multi-access multicarrier relay system, where the source transmits in two time-slots. Under (but not limited to) the indoor power line communication environment, we examine the issue of minimization of the total network transmission power subjecting to QoS constraints expressed as the capacity lower-bound of the data-link from the source to the destination nodes. In addition to demonstrate the fast convergence of the proposed algorithm, the simulation results also show that with respect to the two-hop relay system and the broadcast-and-forward relay system, the proposed general relay system can satisfy the same QoS requirement while consume less total transmission power. |
