  • Error correction systems with modified Viterbi decoding
    Patent number: 5539757
    Abstract: In a communications system, a convolutional encoder encodes data from a data source and a modified Viterbi decoder decodes the encoded data after the encoded dated passes through an error producing channel. The decoder calculates selected metric increments, known as kernel metric increments, for half the states, and selects survivor metrics for all states.
