Multi-source Cooperative MIMO Cognitive Network Based on Distributed Interference Alignment

In this paper we proposed a cooperative MIMO cognitive network scheme. This scheme is composed of multiple source node users and multiple relay node users. Based on distributed interference alignment technology, the proposed scheme has broken the existing research on cooperative MIMO cognitive network of single source node user. Both encoding and decoding processes of the proposed scheme are of linear complexity. We derived the symbol error rate of the proposed scheme . In the scenarios of Rayleigh flat fading channel and MPSK modulation, we simulated the receiving symbol error rate of relay node user. The simulation result of the proposed scheme showed that the symbol error rate become zero when SNR is higher than 10dB.
