Polar codes using dynamic kernels
Min Ye, Alexander Barg · 2015
In the standard polar coding construction, the same kernel is used for every channel transformation. In this paper we propose a new polar coding scheme in which the channel combining transformation is dynamically chosen based on the properties of the virtual channels. We show that for some cases it can improve the finite-length performance of codes. We also show that the dynamic scheme retains some of the main properties of the original polar code construction.
