Abstract: This paper compares Multi-Carrier Modulation (MCM) and Continuous Phase Modulation (CPM) combination, with the use of Frequency Domain Equalization (FDE) for Continuous Phase Modulation (CPM). It is shown that these two constant envelope methods exploit the frequency diversity of multi path channel. In addition, they have 0dB Peak to Average Power Ratio (PAPR) and high power efficiency. However, MCM-CPM combination outperforms applying FDE for CPM due to superior performance of multicarrier systems in frequency selective channels by using orthogonal subcarriers.
Keywords: Multi Carrier Modulation (MCM), Continuous Phase Modulation (CPM), Frequency Domain Equalization (FDE).
