Non-recursive max* operator with reduced implementation complexity for turbo decoding.

In this study, the authors deal with the problem of how to effectively approximate the max* operator when having n >; 2 input values, with the aim of reducing implementation complexity of conventional Log-MAP turbo decoders. They show that, contrary to previous approaches, it is not necessary to apply the max* operator recursively over pairs of values. Instead, a simple, yet effective, solution fo...
