Very Simple Turbo-like Codes

In searching for simple turbo-like codes RA codes are very inspiring. They are perhaps the simplest turbo-like codes. Surprisingly, they achieve good performance too. Simplicity of these codes lends itself to a more comprehensive analysis of their performance. Divsalar et al. have shown the performance of these codes with ML decoding and proven that they can achieve near Shannon limit performance [12]. Moreover, they have proved that it achieves the Shannon limit when the rate goes to zero.
