Apparatus, and associated method, for decoding convolutionally encoded data
Abstract:
An apparatus, and an associated method, for correcting errors in decoded data, decoded by a convolutional decoder, such as an SOVA (Soft Output Viterbi Algorithm). A CRC check is performed upon the decoded data. If the CRC check fails, a conclusion is made that the decoded data contains errors. Portions of the decoded data indicated to exhibit low levels of reliability are toggled with values of most-likely error events. A corrected sequence of the decoded data is formed that corrects for the errors in the decoded data.
