- W2105358401 abstract "In this paper, different power allocation schemes between the source and the cooperating relay nodes are analyzed and numerically evaluated for a two-hop decode-and-forward OFCDM based relay network. A cooperative power allocation ratio λ (=source power/total power) is defined and BER per- formance is evaluated for different values of λ in the relay network. It is shown that there exists an optimal power allocation ratio for different operating environment such as source-to- relay channel gains and time-frequency spreading factors. It is reported that (a) When all three channels (source-to-relay, source- to-destination and relay-to-destination) have equal gains, power ratio is found to be λ ≈ 0.8 (i.e., 80% and 20% of the total power is distributed among source and relay node respectively). The BER performance degrades at a faster rate when λ increases above the optimal value than the decrement at higher Eb/No .( b) For a network with stronger source-to-relay link, the optimal λ remains invariant at higher Eb/No for equal channel gain case; however, the optimal power ratio moves toward lower value of λ at lower Eb/No. (c) The optimal λ remains almost the same with different time-frequency spreading factors." @default.
