Abstract

Iterative decoding and low-density parity-check (LDPC) codes were originally proposed by Gallager in his famous Ph.D. thesis of 1960. However, the power of iterative decoding could not be fully demonstrated due to limitations in computational resources in the 1960s. As a result, iterative decoding had slipped for a long time. It was rediscovered by Berrou, in 1993 in the form of turbo codes, and then independently in the mid 1990s by MacKay in a form of LDPC codes. Using turbo codes and LDPC codes with iterative decoding, it has become possible to realize channel coding schemes that operate close to capacity. Iterative processing techniques have subsequently had a strong impact on coding theory and practice as well as on the entire communication system. In this talk, we will give a brief introduction to modern iterative channel coding including both turbo coding and LDPC coding.

Biography

Yeong-Luh Ueng received the Ph.D. degree in communication engineering from the National Taiwan University, Taipei, Taiwan, in 2001. From 2001 to 2005, he was with a private communication technology company, where he focused on the design and development of various wireless chips. Since December 2005, he has been a member of the faculty of the National Tsing Hua University, Hsinchu, Taiwan, where he is currently an Associate Professor with the Department of Electrical Engineering and the Institute of Communications Engineering. His research interests include coding theory, wireless communications, and communication ICs. He has published 16 IEEE journal papers including 15 full papers. He also has presented 18 technical contributions related to the IEEE 802.16 standard. He was also invited to speak at the 6th International Symposium on Turbo Codes & Iterative Information Processing, one of the most well-known symposiums in the area of error correction coding. He was elected as an honorary member of the Phi Tau Phi Scholastic Honor Society, and he is currently an IEEE member.
