Theses in Progress

Polar Codes for Hard-Decision Decoding


In this internship we will investigate performance and decoding algorithms for polar codes using hard decisions.


Probabilistic Shaping with Low-Density Graph Codes and Message Passing

probabilistic shaping, ldpc, ldgm, belief propagation


In this thesis we will use and develop practical algorithms for lossy source coding (a.k.a. quantization or compression) to construct a probabilistic shaping scheme based on low-density graph codes. 


Shaped Incremental Redundancy HARQ using Polar Codes

polar coding, probabilistic shaping, harq, wireless


The aim of the thesis is to construct a hybrid ARQ coding scheme which employs probabilistic shaing. For both individual concepts, the structure of polar codes provides an amenable fundament. This makes a polarization-based coding scheme an interesting candidate to fuse HARQ with shaping.
