Optimum Non-iterative Turbo-Decoding
Optimum Non-iterative Turbo-Decoding
By observing the structure of the decoder’s trellis a new, non-iterative turbo-decoder based on a super-trellis structure is proposed, which exhibits the same decoding complexity as a conventional convolutional decoder possessing an identical number of trellis states. For the investigated half-rate, memory length-two code the proposed algorithm requires about 0.5dB lower Gaussian channel signal-tp-noise ratio (SNR) than the Maximum A Posteriori (MAP) algorithm using 16 iterations.

Abstract
By observing the structure of the decoder’s trellis a new, non-iterative turbo-decoder based on a super-trellis structure is proposed, which exhibits the same decoding complexity as a conventional convolutional decoder possessing an identical number of trellis states. For the investigated half-rate, memory length-two code the proposed algorithm requires about 0.5dB lower Gaussian channel signal-tp-noise ratio (SNR) than the Maximum A Posteriori (MAP) algorithm using 16 iterations.
