Abstract—Hexagonal Multicarrier Modulation (HMM) is based on arranging the information data in a hexagonal manner in the time-frequency plane to mitigate interference in a doubly dispersive wireless channel. This paper investigates the bit error rate characteristics of this modulation scheme theoretically in the presence of timing offset and carrier frequency offset. The simulation results show clearly that the HMM system can tolerate more offset compared with a conventional OFDM counterpart.
