1. A method for convolutionally encoding digital data with a rate 4/5 convolutional code, comprising the steps of:

  • puncturing a rate 1/2, sixteen state convolutional code based on octal generators 25,37 to rate 4/5 using a puncture map of ##EQU14## wherein ν

    =4; and

    processing an incoming data stream using said rate 4/5 code.
