Abstract
A network-wide interference cancellation scheme estimates channel impulse responses related to Self Interference and the Mutual Interference, then reduces both the Self Interference and the Mutual Interference in the receiver of an Full Duplex device. Full Duplex gains may be capitalized upon and translated into system gain. The scheme is based on an extended Multiple-Input-Multiple-Output (MIMO) treatment of the whole Full Duplex network. The network-wide interference cancellation may be seen to be feasible when a unique pilot signal design and training structure are in place network-wide.
