Abstract
A method and apparatus to select bits for puncturing forward error correcting code frames to synthesize higher code rates. For example, there is provided a method of puncturing a digital data stream that includes a first parity bit stream and a second parity bit stream to generate a punctured bit stream. In one example, the method includes operating a first counting loop to select a first number of punctured bits from the first parity bit stream, comparing the first number of punctured bits with a desired number of bits for the punctured bit stream, and if the first number of punctured bits is less than the desired number of bits, operating a second counting loop to select a second number of punctured bits from the second parity bit stream until the sum of the first number of punctured bits and the second number of punctured bits is equal to the desired number of bits for the punctured bit stream.
