  • Method and apparatus for puncturing a convolutionally encoded bit stream
    Patent number: 6385752
    Abstract: An improved method of puncturing a convolutionally encoded bit stream is provided. Assuming that the convolutionally encoded bit stream has been encoded at rate k/n, puncturing is performed in clusters of n-bit consecutive bits each, these clusters being evenly distributed throughout the encoded bit stream. Improved puncturing matrices are provided for the specific examples consisting of PCS-4 and PCS-5, these being encoding schemes provided in accordance with the EDGE standard.
