| Abstract(in English) | This paper evaluates the required bandwidth to iterative peak power reduction to exactly reduce PAPRs in the proposed intermediary over-sampling method that can reduce computational complexity in OFDMA transmitters. The results of computer simulations show that the required bandwidth is 1.6, 2.0, and 2.7 times of the used signal bandwidth at the iteration number of 1, 2, and 3, respectively. In addition, the results show the iterative peak power reduction method with intermediary FFT/IFFT points can achieve the same BER performance as the usual over-sampling method. |
