Abstract :
An iterative chunk allocation scheme is proposed for SC-FDMA systems on uplink with the MMSE and the ZF equalizers. We propose an indicator related to the capacity to determine the performance of chunks without calculating the log operation. With the help of the proposed indicator, a table is constructed to reduce the complexity for the proposed iterative scheme. The simulation results show that the proposed scheme outperforms the existing schemes and its performances are close to those of the optimum solution.
