These new sequences or codes produce a low peak-to-average power ratio (PAPR) and a low error probability in a code-division multiple access (CDMA) system. All these codes can also be useful in a pre-coded version of an orthogonal frequency-division multiplexing (OFDM) system.engCDMADFTOFDMPerfect DFT Sequencesconference paper10.1109/eurocon.2011.5929376
