Patent

CA 2147816

A method and apparatus are provided for convolutionally encoding digital data with a rate 4/5 convolutional code. A nonoptimal rate 1/2, sixteen-state convolutional code is punctured to rate 4/5 using a puncture map of Image and octal generators 25, 37 wherein v = 4. An incoming data stream is processed using the rate 4/5 code. Punctured rate 3/4 and 6/7 codes are also provided.
