Abstract
A method for encoding or transmitting. In some embodiments, the method includes forming a set of one or more unpunctured codewords by coding a plurality of payload bits at a mother code rate, removing a plurality of punctured bits from the set of one or more unpunctured codewords to form a set of one or more punctured codewords, and transmitting the set of one or more punctured codewords. In some embodiments, the number of punctured bits exceeds a first threshold, or the number of punctured bits exceeds a second threshold.
Claims20
A method, comprising:
- forming a set of one or more unpunctured codewords by coding a plurality of payload bits at a mother code rate;
- determining a number of bits to remove, such that the number of bits is greater than a first threshold and a ratio of a number of shortening bits to the number of bits to remove is less than the mother code rate;
- puncturing the set of one or more unpunctured codewords to remove a number of bits to form a set of one or more punctured codewords;
- and
- transmitting the set of one or more punctured codewords.
A system, comprising:
- a wireless station, comprising a processing circuit,
- the processing circuit being configured to:
- form a set of one or more unpunctured codewords by coding a plurality of payload bits at a mother code rate;
- determine a number of bits to remove, such that
- the number of bits is greater than a first threshold and a ratio of a number of shortening bits to the number of bits to remove is less than a the mother code rate
- puncture the set of one or more unpunctured codewords to remove a number of bits to form a set of one or more punctured codewords;
- and
- transmit the set of one or more punctured codewords.
