Comparison of Schemes for Joint Subcarrier Matching and Power Allocation in OFDM Decode-and-Forward Relay System


The combination of relay system and orthogonal frequency division multiplexing (OFDM) modulation is a promising way to increase capacity and coverage area. We consider several joint subcarrier matching and power allocation schemes to maximize channel capacity, where the relay strategy is decode-and-forward. We formulate the optimally joint subcarrier… (More)
