| Abstract: | An orthogonal frequency division multiplex-cooperative complex field network coding(OFDM-CCFNC) algorithm is proposed, which combines orthogonal frequency division multiplex and cooperative complex field network coding. The system frame error rate and spectrum efficiency are theoretically analyzed, and the simulation results show that the proposed algorithm overcomes the influence of the frequency selectively fading of channels and improves system spectrum efficiency. Finally, an optimal system power allocation scheme is also presented based on the minimum system frame error rate for the proposed algorithm. |
