Abstract
Inverse function of min*:min*− (inverse function of max*:max*−). Two new parameters are employed to provide for much improved decoding processing for codes that involve the determination of a log corrected minimal and/or a log corrected maximal value from among a number of possible values. Examples of some of the codes that may benefit from the improved decoding processing provided by the inverse function of min*:min*− (and/or inverse function of max*:max*−) include turbo coding, parallel concatenated trellis coded modulated (PC-TCM) code, turbo trellis coded modulated (TTCM) code, and low density parity check (LDPC) code among other types of codes. The total number of processing steps employed within the decoding of a signal is significantly reduced be employing the inverse function of min*:min*− (and/or inverse function of max*:max*−) processing.
