Advanced coding techniques for 5G communications systems and beyond

Future wireless systems will build a hyper-connected society that encompasses around 7 trillion wireless connections. This requires devising a new air interface where heterogeneous devices working under different frequency bands and transmit power limits will coexist. As a part of this goal, the mobile industry ecosystem and academic researchers are working together on several technical fronts to develop and standardize the needed air interfaces (for example the fifth generation wireless systems: 5G). A vital component of any modern communication system is channel coding which protects data against the unwanted surrounding noise/interference. Considering the stringent performance measures of future wireless systems (extreme data rates, very high energy efficiency and low latency), research labs and telecommunication companies around the world are focused on devising practical and efficient channel coding solutions. In particular, polar codes and low-density parity check (LDPC) codes are at the centre of attention. In fact, in the latest 3GPP meeting (November 2016), it was decided that both polar codes and LDPC codes will be used in 5G. The panel also encouraged researchers to work around existing problems and optimization of these codes.This proposal, aims at developing low-complexity capacity-approaching polar and LDPC codes under practical assumptions. Our focus will be on the applications of polar and LDPC codes in the 5G networks and other emerging technologies (e.g., Internet of Things). This work will be done together with our industry partner, TELUS Corporation (a telecommunication company with 12.5 million customer connections and close to $12.5 billion annual revenue)Canada has been a major international contributor in the world of ICT. The Canadian ICT sector consists of about 36,000 companies that directly generate about 5% of the national GDP. Any new technology generated in this project would benefit the Canadian ICT companies, reinforcing their global competitiveness.
