Abstract
Systems and methods generate corrected channel transfer functions by cross-correlation nulling. In an example system, a first receiver node (which may be a wireless base station) receives first expected reference signal information associated with an interfering transmitter node (which may be a wireless user equipment) and creates a correction matrix based on the first expected reference signal information associated with the interfering transmitter node and on second expected reference signal information associated with an intended transmitter node. The correction matrix can then be applied to an estimated channel transfer function associated with a received transmission from the intended transmitter node to generate a corrected channel transfer function associated with the received transmission from the intended transmitter node. The first receiver node can use the corrected channel transfer function in decoding received transmissions including, for example, use in performing interference resolution.
