Patent ID: 8411773

Claim:
An equalization method for distributed resource allocation in multi-carrier systems having a plurality of user equipment (UEs), comprising: providing a channel estimation module configured for obtaining a channel feature matrix including channel parameters and a matrix that characterizes inter-carrier interference (ICI) coming from the plurality of UEs; using the channel estimation module for defining a channel model wherein received signals are described as a product of transmitted signals with the channel feature matrix that includes channel parameters and a matrix that characterizes the ICI coming from the plurality of UEs, wherein the channel estimation module is used in an iterative estimation process including iterative linear channel estimation; obtaining the channel feature matrix including the channel parameters and ICI by using the channel estimation module as part of an estimation process that is based on the defined channel model; using an inversion module for an inverting sum of the channel feature matrix plus the matrix that characterizes the ICI coming from the plurality of UEs, and therein providing an inverted channel response matrix; and performing channel equalization.
