Abstract :
In the present paper, we propose a new modulation called continuous-phase parallel-combinatory high-compaction multicarrier modulation (CPPC/HC-MCM). The CPPC/HC-MCM employs the technique of continuous phase modulation (CPM) and avoids the amplitude gaps between two successive signals to enhance the property of spectral efficiency of conventional PC/HC-MCM. The results show that the CPPC/HC-MCM achieves a smaller bit-error rate (BER) than conventional (unmodulated) PC/HC-MCM for large signal-to-noise ratio at a common spectral efficiency less than about 0.33.
