INTERFERENCE ALIGNMENT IN A NETWORK WITH ASYMMETRICAL CHANNEL DIMENSIONS

Systems and methods for full-duplex communication in a communications network, including generating a combined channel matrix including two or more channel matrices and determining a null space and a basis for the combined channel matrix. Common, individual, and disjoint vector spaces are determined, and common vector space is determined for each of one or more receiving nodes and each or one or more transmitting nodes, disjoint vector spaces for each of the one or more nodes are determined based on the common vector space for each of the one or more nodes, and individual vector spaces are determined based on the common and the disjoint vector spaces. Signals are mapped at each of the nodes to determine corresponding vector spaces; and interference alignment is performed in common vector spaces and zero forcing in disjoint vector spaces using a hardware processor.
