Abstract:

A novel interference cancellation algorithm without requiring extra channel information, namely the information between user equipment and cooperated cells  is proposed. By investigating the interference processed at the receiver in coordinated multipoint transmission single user multiple-input multiple-output (CoMP-SU-MIMO) transmission and the characteristics of dual polarized channel, combined with the existing limited feedback technologies, a novel interference cancellation algorithm was proposed. Utilizing the eigenvector’s orthogonality of polarized channel, the proposed algorithm could achieve better performance on interference cancellation, and the algorithm complexity can be reduced as well.
