This thesis proposes the design of Abject Density Parity Halt (LDPC) codes for cases where coded modulation is misused. We design these codes by extending the idea of Density Evolution (DE) that has been introduced as A powerful tool to analyze LDPC codes.Author: Ravi NarayanaswamiCited by: Publish Year: 2001
