Abstract:
A method for cancelling inter-node interference at a victim node is disclosed, which method may be executed as instructions on a machine, where the instructions are included on at least one computer readable medium. The method can include the victim node receiving downlink signal information from an aggressor node. The victim node can estimate a channel impulse response for a channel between the aggressor node and the victim node using the downlink signal information. The victim node can estimate an inter-node interference signal for the channel using the downlink signal information and the channel impulse response. The victim node can receive an uplink signal from a wireless device, wherein the downlink signal information is received prior to the reception of the uplink signal. The victim node can subtract the estimated inter-node interference signal from the uplink signal to form an inter-node interference compensated uplink signal to substantially cancel the inter-node interference from the aggressor node in the uplink signal.
