Sarah Johnson received the B.E. (Hons) degree in electrical engineering in 2000, and PhD in 2004, both from the University of Newcastle, Australia. She then held a postdoctoral position with the Wireless Signal Processing Program, National ICT Australia before returning to the University of Newcastle where she is a senior research fellow. Sarah's research interests are in the field of error correction and information theory, and in particular low-density parity-check codes, repeat-accumulate codes, iterative decoding algorithms and network coding. She is the author of a book on iterative error correction published by Cambridge University Press.

Cambridge book on iterative errror correction

Iterative Error Correction
Turbo, Low-Density Parity-Check and Repeat-Accumulate Codes
Sarah J. Johnson
356 pages, Cambridge University Press, 2010

Iterative error correction codes have found widespread application in cellular communications, digital video broadcasting and wireless LANs. This self-contained treatment of iterative error correction presents all the key ideas needed to understand, design, implement and analyse these powerful codes. Turbo, low-density parity-check, and repeat-accumulate codes are given equal, detailed coverage, with precise presentations of encoding and decoding procedures. Worked examples are integrated into the text to illuminate each new idea and pseudo-code is included for important algorithms to facilitate the reader's development of the techniques described. For each subject, the treatment begins with the simplest case before generalizing. There is also coverage of advanced topics such as density-evolution and EXIT charts for those readers interested in gaining a deeper understanding of the field. This text is ideal for graduate students in electrical engineering and computer science departments, as well as practitioners in the communications industry.
