Claim 19:
20. In a receiver, a method for iteratively decoding an encoded message in an analog signal to achieve a decoded message, wherein
(i) the encoded message results from an encoding method that comprises:
including in the message an error decoding code, according to an error detection scheme;
encoding the message in Turbo Codes, and
modulating the encoded message for transmission to the receiver as a plurality of analog values in the analog signal; and

(ii) the method for iterative decoding comprises:
(a) based on channel condition, determining a required number of iterations necessary to achieve a predetermined bit error rate in the decoded message;
(b) after completing a predetermined number of iterations of the iterative decoding that is less than the required number of iterations, examining the error detection code to determine whether the error detection code indicates that no error has occurred during transmission; and
(c) when it is determined in the iteration that no error has occurred during the transmission, terminating the iterative decoding process.
