Abstract :
A new joint source channel decoding technique called channel coded optimal estimation (CCOE) is introduced. Bit-reliability information of the received source-encoder bits and the redundant bits of a systematic channel code are combined with the source-signal statistics to calculate the a-posteriori probabilities for all possibly transmitted codewords. The probabilities are used to estimate the transmitted signal at the receiver
