Patent ID: 8243709

Claim:
A method for mitigation of interference in a cellular communication system, comprising: in a receiver in a cell of a system; deriving for a first channel in the cell a first signal representative of a first channel transfer function; deriving for at least a second channel originating in a different cell a second signal representative of a second channel transfer function, wherein the second signal includes a first code and a second code, and deriving the second signal includes: deriving the first code, deriving a channel impulse response, deriving a training data sequence common to a plurality of channelisation codes associated with the different cell in response to receiving a cell identifier, and deriving the second code comprising a tentative code in place of determining an actual channelisation code used in the different cell from among the plurality of channelisation codes, wherein the tentative code is multiplexed with zeros to form the second code; and performing multi-user detection using the first signal and the second signal.
