Topic Overview:
Low-density parity-check (LDPC) codes form a subclass of linear block codes which can be represented by sparse parity check matrices. Due to their capacity-achieving performance, they are adopted by different standards such as Digital Video Broadcasting Standard , WIMAX Standard, IEEE 802.16e, and WiFi Standard IEEE 802.11n. Also, these standards consider the use of link adaptation based on Adaptive Modulation and Coding (ACM) and Hybrid Automatic Repeat reQuest (HARQ). This requires the design of various LDPC code rates and coded block lengths with uniform encoding/decoding structure.
Objectives:
- Reviewing the different types of LDPC
- Investigating the different construction techniques of LDPC that lead to an accurate code profile.
- Comparing the encoding complexity of different construction techniques.
- Proposing new construction techniques.
- Studying the performance of the newly designed codes.
Outcomes:
- One to two research papers per student to be submitted to prestigious conferences and journals
- One to two M.Sc. theses
Resources:
- Approximately LE3000 to cover the registration or publication fees in International conference per paper. (Average registration fees is $600) in addition to travel expenses.
- Two to three M,Sc. Students
- Software simulation tools such as Math lab or similar
