Abstract :
We develop new, low-complexity turbo codes suitable for bandwidth and power limited systems. These codes are constructed as an extension of repeat-accumulate codes to high-level-modulations. Two design criteria are proposed, based on maximum-likelihood decoding and on Gaussian density evolution in iterative decoding
