A device (102) supports error correction. A receiver (120) is configured to receive data over a communications link. A decapsulator (122) is coupled to the receiver and configured to create datagrams. A decoder (124) is coupled to the decapsulator and configured to store the datagrams in a table and to create codewords, the decoder storing the datagrams in table columns to create codewords in table rows. A user interface (126) is coupled to the decoder and configured to render images corresponding with the datagrams on the user interface. Advantages of the invention include efficient signal processing and prolonged battery life in mobile wireless devices.
