Faculty of Engineering, LTH, Elektro- och informationsteknik

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has 40 000 students and 7 400 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

LTH forms the Faculty of Engineering at Lund University, with approximately 9 000 students. The research carried out at LTH is of a high international standard and we are continuously developing our teaching methods and adapting our courses to current needs.
Subject description
For the large block length scenario eMBB in the next generation of cellular systems 5G, low-density parity-check (LDPC) codes have been chosen to replace the LTE turbo codes. The uRLLC scenario, on the other hand, puts strong requirements on low block error rates at short to moderate block lengths. Under these conditions it is not clear that LDPC codes with BP decoding are a good solution. The purpose of this project is to investigate efficient coding schemes for this scenario.

Work duties
  • To investigate how CRCs can be used to improve the performance of  short LDPC codes.
  • To develop efficient list decoding algorithms for CRC-aided LDPC codes and study the trade-offs between performance and complexity. 
  • To use ideas from stochastic decoding to improve performance of short codes beyond BP decoding.
  • To implement the considered encoding and decoding algorithms in software and evaluate the performance with computer simulations.

The department of electrical and information technology has vast experience in the field of LDPC codes and codes on graphs and iterative decoding in general.

Qualification requirements
Applicants must have:

  • A PhD or equivalent research qualification within the subject of the position.
  • Very good oral and written proficiency in English.
  • Deep experience of channel coding, documented in the form of scientific publications.

Other qualifications
  • Ability to conduct both theoretical and experimental research in the subject area described above.
  • Experience with the design and analysis of LDPC codes and iterative decoding as well as simulation of communication systems in Matlab/C.

Consideration will also be given to good collaborative skills, drive and independence, and how the applicant’s experience and skills complement and strengthen ongoing research within the department, and how they stand to contribute to its future development.
