Coded Multicasting Scheme for Finite Fractional Caching

Description

Implement a polynomial-time algorithm based on greedy local graph-coloring while keeping the same content packetization.

Compare the performation with other graph-coloring algorithm, do the run-time measurement and try parallelzation of the algorithm to reduce the run-time.

List decoding of Interleaved Goppa Codes

Keywords:
decoding; implementation

Description

Goal: implement a list decoding algorithm for binary interleaved Goppa codes and derive the decoding radius.

Fundalmentals on Goppa codes can be found in [2, Chap 12.3], [3, Chap 2].

Fundalmentals on list decoding can be found in [4, Chap 12], [5, Chap 9].
