ABSTRACT:
A receiver is to receive an encoded data block that was encoded using a convolutional encoder and includes source bits and error detection bits. The receiver may include a Viterbi decoder, a de-mapper and an error detection unit. The error detection unit is to determine whether an error correction capability of the Viterbi decoder is sufficient to recover the source bits from the encoded data block. The Viterbi decoder is to decode the encoded data block only if the encoded data block is not free of errors and if the error correction capability of the Viterbi decoder is sufficient to recover the source bits from the encoded data block.
