Abstract :
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 bandwidth efficiency compared to an ordinary OFDM system. Further, the peak to mean power ratio of the PC-OFDM system is lower than for OFDM, which reduces the problem of designing linear power amplifiers
