Since wireless links are relatively weak, bandwidth is relatively limited and there is no support for fixed infrastructures, clustered Ad Hoc networks are easy to be disturbed by channel noises. Therefore, clustered Ad Hoc networks have poor channel transmission performance and are unable to enter the large-scale practical application stage in a short period of time. To improve the channel transmission performance of clustered ad hoc networks and the practical value of the cooperative Multi-Input Multi-Output (MIMO) technology, a Cooperative MIMO transmission mechanism based on Phase-Inversion Symmetric Method (PISM-CMIMO) is proposed, which absorbs the advantages of phase-inversion symmetric method and cooperative MIMO technology and makes full use of the correlation of the adjacent channel noises.
