CPPC/HC-MCM employs the technique of continuous-phase modulation (CPM) and avoids the formation of amplitude gaps between two successive signals to enhance the spectral efficiency of conventional PC/HC-MCM. Results of simulations show that CPPC/HC-MCM is spectrally efficient and achieves a smaller bit error rate than conventional (unmodulated) PC/HC-MCM at a common spectral efficiency even if the peak-to-average power ratio is considered.}, pages = {802--805}, title = {Continuous-Phase, Unmodulated Parallel-Combinatory High-Compaction Multicarrier Modulation}, volume = {E94-B}, year = {2011} }
