چکیده
SUMMARY A new type of modulation called continuous-phase parallel-combinatory high-compaction multicarrier modulation (CPPC/ HC-MCM) is proposed. 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.

A Novel Modulation with Parallel Combinatory and High Compaction Multi-Carrier Modulation
SUMMARY In this paper, we propose a new modulation named parallel combinatory/high compaction multi-carrier modulation (PC/HC-MCM) using the techniques of parallel combinatory orthogonal frequency division multiplexing (PC-OFDM) and high compaction multi-carrier modulation (HC-MCM). Two types of PC/HC-MCM systems, which are named as modulated PC/HC-MCM system and (unmodulated) PC/HC-MCM system ...
متن کاملInterleaved PC-OFDM to reduce the peak-to-average power ratio
Parallel combinatory orthogonal frequency division multiplexing (PC-OFDM) yields lower maximum peak-toaverage power ratio (PAR), higher bandwidth efficiency and lower bit error rate probability (BER) on Gaussian channels compared to OFDM systems. However, PC-OFDM does not improve the statistics of PAR significantly. In this paper, the use of a set of fixed permutations to improve the statistics...

A parallel combinatory OFDM system (PC-OFDM) is proposed. The proposed system is able to obtain a higher bandwidth efficiency than an ordinary OFDM system. The bit error rate performance is analyzed and simulated. On a Gaussian channel and on known time invariant channels the PC-OFDM system can obtain lower bit error rates than ordinary OFDM. In some cases we can at the same time increase the b...
متن کاملParallel combinatory OFDM signaling
In this paper, A Parallel Combinatory-Orthogonal Frequency Division Multiplexing (PC-OFDM) system is proposed and analyzed. The proposed system selects at each symbol interval a subset of the available sub-carriers, and the selected sub-carriers are modulated by points from an M-PSK signal constellation. PC-OFDM systems can be designed to have lower Peak to Average Power Ratio (PAPR), higher ba...
