Abstract :
In this paper, subcarrier-index modulation (SIM) is developed as a new way of vector modulation for interleaved frequency division multiple access (IFDMA) systems. We show that the combination of SIM and IFDMA can have the advantage of both low peak-to-average power ratio (PAPR) and better system performance. According to our simulation results, the proposed SIM based vector modulated IFDMA system performs better than traditional IFDMA system, while remaining the low PAPR property.
