Methods and apparatus for enabling effective decoding of rate-compatible punctured codes are presented herein. A puncturing component can derive one or more partial puncturing patterns and corresponding decoding matrices/graphs that represent punctured code from a parity check matrix/graph of a mother code and a puncturing pattern specified for the mother code. Further, a rowcombining component can combine rows of the parity check matrix/graph based on the derived one or more partial puncture patterns. Further, the rowcombining component can create at least one decoding matrix/graph to represent the punctured code based on the combined rows. In addition, a selection component can select a decoding matrix/graph from the created at least one decoding matrix/graph that does not contain a girth-4 cycle.
