American Journal of Computer Sciences and ApplicationsIn this paper, a DFT- based OFDMA with phase modulation (DFT-OFDMA-PM) system is proposed. The proposed system exploits the advantages of PM, the constant envelope (CE) signal, and the ability to improve the diversity of multipath channels. The performance of the proposed system in terms of bit error rate (BER) is studied and investigated using simulation. An investigation of the proposed system, the DFT-OFDMA-PM, results is carried and compared to the recently proposed DCT-OFDMA-PM system and the conventional systems without PM. Moreover, the key parameter, the modulation index, which affects the performance of the PM systems, is also studied and the optimum value is chosen via simulation. The simulation results for the proposed system show the effectiveness of the proposed system for broadband communications.
