摘要
Techniques and apparatus are provided for efficiently generating multiple lifted low-density parity-check (LDPC) codes for a range of block lengths and having good performance. A method for wireless communications by a transmitting device generally includes selecting integer lifting values for a first lifting size value Z, selected from a range of lifting size values, wherein the selected integer lifting value is greater than a maximum lifting size value of the range of lifting size values; determining one or more integer lifting values for generating at least a second lifted LDPC code having a second lifting size value based on an operation involving the second lifting size value and the selected one or more integer lifting values for generating the first lifted LDPC code; encoding a set of information bits based on the second lifted LDPC to produce a code word; and transmitting the code word.
