Patent ID: 8145178

Claim:
A turbo decoding module for use within a wireless Radio Frequency (RF) transceiver, the turbo decoding module comprising: a memory interface communicatively coupled to a memory storing a plurality of sets of Incremental Redundancy (IR) samples produced from an inbound baseband signal; a turbo decoder core for retrieving at least one of the plurality of sets of IR samples from the memory via the memory interface, forming a turbo code word from the at least one set of IR samples, turbo decoding the turbo code word, and producing inbound data from the turbo code word; and an output buffer for outputting the inbound data; wherein the turbo decoder core further maintains a set of metrics while turbo decoding the turbo code word, identifies a chosen metric of the set of metrics and normalizes each other metric of the set of metrics based upon the chosen metric.
