Simplified Log-MAP Algorithm for Very Low-Complexity Turbo Decoder Hardware Architectures

Motivated by the importance of hardware implementation in practical turbo decoders, a simplified, yet effective, n-input max* approximation algorithm is proposed with the aim being its efficient implementation for very low-complexity turbo decoder hardware architectures. The simplification is obtain...
