SYSTEM AND METHOD FOR COMMUNICATING WITH LOW DENSITY PARITY CHECK CODES

摘要

The present invention provides an approach for FEC encoding based on intermediate code block lengths not associated with any supported mother FEC code. A first string of k2 data bits is received. The first string of data bits is encoded to generate an N2 bit code block for transmission over a channel of a wireless communications network. The first data bit string is encoded based on a supported (N1, k1) forward error correction (FEC) code of a code rate R=k1/N1, configured to encode a string of data bits of a length k1 bits to generate a code block of a length N1 bits. To facilitate the encoding of the first string of data bits based on the (N1, k1) FEC code, the encoding comprises padding, repeating and/or puncturing the first string of data bits and a resulting N1 bit code block to generate the N2 bit code block.

1. A method comprising:
receiving a first string of data bits of a length k2 bits; and encoding the first string of data bits to generate a code block of a length N2 bits for transmission over a channel of a wireless communications network; wherein the first string of data bits is encoded based on a supported (N1, k1) forward error correction (FEC) code of a code rate R=k1/N1 configured to encode a string of data bits of a length k1 bits to generate a code block of a length N1 bits; and wherein, to facilitate the encoding of the first string of data bits based on the (N1, k1) FEC code, the encoding comprises one or more of padding, repeating and puncturing the first string of data bits and a resulting N1 bit code block to generate the N2 bit code block.
