A novel two time slots Orthogonal Frequency Division Multiplexing-Index Modulation (OFDM-IM)- aided cooperative relaying protocol is proposed for Cooperative Cognitive Radio Networks (CCRN). In the proposed scheme, OFDM-IM technique is used at the Secondary User (SU) to split the transmission space into the signal constellation domain and the index domain. Specifically, the Secondary Transmitter (ST) of SU acts as a Decode-and-Forward (DF) relay to transmit the information of the Primary User (PU) in the signal constellation domain, while the information bits of SU are carried by the index domain. Through this design concept, the mutual interference between the PU and SU can be avoided. Upper bounds on the Bit Error Probabilities (BEPs) of the PU and SU are analytically derived. The influence of ST’s location to the BER performance of PU and SU is also analysed. Several numerical results and discussions are provided to substantiate the theoretical analysis, and it is shown that the proposed protocol is a viable candidate for OFDM-based CR networks since it can enhance the BER performances of both PU and SU.
