  • Abstract
    In this study, a method is presented for constructing convolutional codes of variable rate and decoding complexity. Starting with an (n,1,m) mother code, the techniques of puncturing and path pruning are utilized in order to construct large families of convolutional codes of various code rates and complexity. Decoding is performed using the trellis of the mother code.
