Abstract

A data communication method for puncturing of parity bits defining all parity data for a minimum code rate generated by an encoder is disclosed. The method initializes an accumulator associated with the parity bits to an initial value, and for each parity bit increments the accumulator by a increment value and determines if the accumulator has overflowed. If the accumulator overflows, at least one of the parity bits is selected for transmission.
