Abstract  Abstract

claims a method for eliminate inter-node interference at the victim node the method can be used as instruction is executed on a machine wherein the instructions are included on at least one computer readable medium. The method may include victim node receiving downlink signal from invader node information. the victim node can use the downlink signal information to estimate a channel impulse response of the channel between invader node and the victim node. the victim node can use downlink signal information and a channel impulse response estimate for a node interference signal of the channel. the victim node capable of receiving uplink signals from wireless device wherein the downlink signal information is received before receiving the uplink signal. the victim nodes can be removed from the uplink signal estimated interference signal between nodes to form a node an uplink interference compensation signal to substantially eliminate the invader from node inter-node interference in the uplink signal.

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.
