Abstract: A method for performing polar decoding with aid of notation transformation and associated polar decoder are provided. The method includes: transforming input signals from a 2's complement notation to a signed magnitude notation to generate transformed input signals, wherein during the polar decoding, a plurality of first sub-operations and a plurality of second sub-operations are performed to generate decoding results of the transformed input signals; performing a first sign processing to generate a sign result of a first sub-operation within the plurality of first sub-operations; performing a first magnitude processing to generate a magnitude result of the first sub-operation within the plurality of first sub-operations; performing a second sign processing to generate a sign result of a second sub-operation within the plurality of second sub-operations; and performing a second magnitude processing to generate a magnitude result of the second sub-operation within the plurality of second sub-operations.
