The promise of essentially error-free information transmission is a cornerstone of digital communications. Next-generation applications demand increasingly effective error correction, yet traditional systems fall well short of fundamental capacity limits established some fifty years ago. Exciting breakthroughs in the mid-1990s delivered capacity-approaching codes on graphs employing iterative decoding algorithms, including low-density parity-check (LDPC) codes. This project applies techniques from discrete mathematics to design structured LDPC coding schemes for widespread implementation. Outcomes of this research will be new LDPC codes, encoding algorithms and analysis techniques for applications including wireless networks, data storage and Internet communications.Read moreRead less

Space-time coding for multiple transmit and multiple receive antennas is the enabling technology for future wireless communication systems. Multiple antennas provide independent transmission paths resulting in an increased channel capacity without requiring costly additional bandwidth. Space-time block codes lead to the simplest receiver structures and thus to the most economical solutions. The currently known codes are based on the work of one of the CIs, but so far only a small part of that work has been utilised. We aim to fully exploit the potential of this theory and move the performance of wireless systems towards their theoretical limits.Read moreRead less
