In this study, an achievable rate of dual-hop non-regenerative OFDM (Orthogonal Frequency Division Multiplexing) relay systems with subcarrier mapping and power allocation to both source and relay nodes is evaluated.
We prove the optimality of rank ordered subcarrier mapping according to the product of channel gain and allocated power and evaluate the improvement of achievable rate by the mapping function for several power allocation methods.
We numerically confirm that the combined method of rank ordered subcarrier mapping based on channel gain and sub-optimal power allocation which satisfies KKT (Karush-Kuhn-Tucker) conditions is very close to the jointly optimized method. |
