An apparatus and method for error correction based on soft decision bits and multiple hypotheses includes: maintaining a plurality of previous single bit-flip hypotheses, each hypothesis including a respective bit-flip, a respective pre-flip bit confidence, and a respective hash responsive to the respective bit-flip; receiving a bit and a corresponding bit confidence; comparing the received bit confidence with a highest pre-flip bit confidence of the maintained plurality of single bit-flip hypotheses; and if the received bit confidence is less than the highest pre-flip bit confidence, forming a new single bit-flip hypothesis and replacing a prior bit-flip hypothesis having the highest pre-flip bit confidence with the new hypothesis.

Error correction using soft decision bits and multiple hypotheses

A page scanning device configured to generate a sequence mask for an expected frequency hopping sequence, select a first tone among a plurality of detected tones, first determine whether the first tone is included within an expected hop sequence, generate a first tone template in response to determining that the first tone is included within the expected hop sequence, align the first tone template with the plurality of detected tones based on the first tone, second determine whether the first tone template matches the plurality of detected tones, and detect a valid frequency hopping sequence in response to determining that the first tone template matches the plurality of detected tones.

A data bus interface may include a history buffer and a serializer. The history buffer may store bits representing a history of data recently transmitted on the data bus. The serializer may be configured to modify an input bit sequence containing original bits by interspersing padding bits with the original bits to suppress noise at one or more target frequencies. The serializer may output the modified input bit sequence on the data bus. Each padding bit of the plurality of padding bits may be generated based on values of at least two bits stored in the history buffer.
