Abstract
Differential puncture patterns are used for puncturing and de-puncturing codewords transmitted over a communication channel. The puncture pattern comprises a series of successive differential indices or offsets corresponding to differences between successive bit indices in an absolute bit index sequence. The differential puncture patterns are used at the transmitter to select bits of a codeword for transmission over the communication channel. At the receiver, the differential puncture pattern is used to determine the bit positions of received bits in a de-punctured codeword.
