Abstract:
Forward Error Correction (FEC) techniques that generate independently decodable resource blocks are beneficial for Successive Interference Cancellation (SIC) demodulation. One FEC technique for generating independently decodable resource blocks includes mapping locally decodable FEC codeblocks into unique resource blocks such that substantially all of the bits of the FEC codeblock are carried within a single resource block. The locally decodable FEC codeblocks can be generated from different FEC encoding modules or from a common FEC encoding module. Another technique for generating independently decodable resource blocks includes encoding a stream of information bits into low-density parity-check (LDPC) codeblocks having high ratios of inward peering parity bits. These high ratios of inward peering parity bits allow substantial portions of each LDPC codeblock to be decoded independently from information carried by other LDPC codeblocks.
