Low-density parity-check codes for nonergodic block-fading channels. IEEE Trans. Inf. Theory. 2010;56(9):4286-300. DOI 10.1109/TIT.2010.20538900018-9448http://hdl.handle.net/10230/20436We design powerful low-density parity-check (LDPC) codes with iterative decoding for the block-fading channel. We first study the case of maximum-likelihood decoding, and show that the design criterion is rather straightforward. Since optimal constructions for maximum-likelihood decoding do not perform/nwell under iterative decoding, we introduce a new family of full-diversity LDPC codes that exhibit near-outage-limit performance under iterative decoding for all block-lengths. This family competes favorably with multiplexed parallel turbo codes for nonergodic channels.application/pdfeng© 2010 IEEE. Personal use of this material is permitted.
