  • Decoding of turbo codes using data scaling
    Patent number: 6393076
    Abstract: A method 100 for improved decoding of received convolutionally coded input data uses data scaling to provide near ideal turbo decoding. The method includes a first step of loading 102 a portion of the input data into a buffer. A next step includes calculating 104 a mean of the data in the portion of the input data. A next step includes computing 106 a root-mean-square value of the portion of the input data using the mean from the calculating step. A next step includes deriving 108 a scaling factor from the root-mean-square value of the computing step, and a next step includes scaling 110 the portion of input data by the scaling factor of the deriving step.
