Abstract :
We consider turbo decoding of parallel concatenated single parity check (SPC) (K+1,K) codes, with row-column interleaving. The existence and uniqueness of the asymptotic probability density evaluated with the turbo algorithm is proved for every length K and every signal-to-noise ratio (SNR).
