Abstract

Degree of freedom of MIMO interference channels with constant channel coefficients is studied in this paper. An asymmetric interference alignment and cancelation scheme is proposed for the 3-user MIMO interference channels with constant channel coefficients. With M antennas at each transmitter and N antennas at each receiver, the total degree of freedom (M+2N)/2 can be achieved by the proposed scheme for N <; M ≤ 2N.
