A novel system named parallel combinatory/high compaction multi-carrier modulation(PC/HC-MCM) system was proposed based on techniques of high compaction multi-carrier modulation(HC-MCM) and parallel combinatory OFDM(PC-OFDM).Compared with PC-OFDM
PC/HC-MCM can dramatically improve the bandwidth efficiency of PC-OFDM system.On the other hand
it simulated the performance of two different PC/HC-MCM systems which can be developed to apply in multi-carrier systems.
