Reduced complexity turbo decoding scheme

A reduced complexity turbo decoding scheme combines elements from two MAP (Maximum a posteriori) algorithms, namely a LogMAP algorithm and a max-LogMAP algorithm. Forward and backward recursive metrics are computed in accordance with the max-LogMAP algorithm, while output extrinsic LLR (Log Likeliho...

Zusammenfassung:A reduced complexity turbo decoding scheme combines elements from two MAP (Maximum a posteriori) algorithms, namely a LogMAP algorithm and a max-LogMAP algorithm. Forward and backward recursive metrics are computed in accordance with the max-LogMAP algorithm, while output extrinsic LLR (Log Likelihood Ratio) values are computed in accordance with the LogMAP algorithm.
