METHOD AND APPARATUS FOR LOW-COMPLEXITY INTERFERENCE CANCELLATION IN COMMUNICATION SIGNAL PROCESSING Russian patent published in 2014 - IPC H04L25/03 H04L1/00 

Abstract RU 2510582 C2

FIELD: radio engineering, communication.

SUBSTANCE: in one aspect, flexible scaling may be understood as attenuating the amount of interference cancellation applied by a receiver, depending on the dynamically changing received signal quality at the receiver. More attenuation is applied at lower signal quality since the hard decisions are less reliable at lower signal qualities, while less (or no) attenuation is applied at higher signal qualities, reflecting the higher reliability of the hard decisions at higher signal qualities. Signal quality may be broken down into ranges, with different values of the flexible scaling factor used for each range.

EFFECT: low complexity of interference cancellation.
