Resource Allocation in OFDM Systems -- Efficiency as Basis for Allocation and Initialization


M. Reyer, A. Sch├Ąper, R. Mathar,


        Rate and power allocation in OFDM systems is discussed extensively in literature. These approaches are either based on a finite set of realizable rates or make use of a continuous rate-power function.
The motivation of this correspondence was to investigate how to transfer efficiently continuous rate allocations to realizable ones. To increase performance, we suggest to skip some realizable rates. Then, our proposed algorithm for single-user resource allocation on the set of realizable rates produces the same allocation independent of the initialization. This algorithm achieves the optimal solution when the given lower and upper bound for the optimum are identical. Furthermore, we suggest an initialization procedure which comes very close to this allocation. Finally, we present simulation results to assess some quantity measures of our approach.
