Non-contiguous CI/OFDM: A new data transmission scheme for cognitive radio context

In this paper, the authors propose to apply non-contiguous CI/OFDM (NC-CI/OFDM) as a new data transmission scheme for CR context. Computer simulation results confirm that the proposed NCCI/OFDM system can bring desirable BER performance and low PAPR compared with the traditional NC-OFDM.
