| Abstract | We address the problem of joint source-channel coding when variable length codes are used for information transmission over a discrete memoryless channel. The data transmitted over the channel are interpreted as pairs (m k ; t k ); where m k is the message generated by the source and t k is the time instant when the transmission of the k-th codeword begins. The decoder constructs an estimate of the transmitted sequence of pairs, and the k-th decoding error is introduced as the event that the pair (m k ; t k ) does not belong to this sequence. We describe the maximum likelihood decoding algorithm and prove a lower bound on the exponent of decoding error probability. For a subclass of discrete memoryless sources and discrete memoryless channels this bound is asymptotically tight. |
