Abstract :
Optimal puncturing ratios for parallel concatenated codes with two or more constituent codes are found using extrinsic information transfer functions. These ratios minimize the signal-to-noise ratio convergence threshold and provide additional degrees of freedom for constructing codes with low thresholds over a wide range of code rates.
