LP-decodable multipermutation codes
Xishuo Liu, Stark C. Draper
In this paper, we introduce a new way of constructing and decoding multipermutation codes. Multipermutations are permutations of a multiset that may consist of duplicate entries. W…
The ADMM penalized decoder for LDPC codes
Xishuo Liu, Stark C. Draper
Linear programming (LP) decoding for low-density parity-check (LDPC) codes proposed by Feldman et al. is shown to have theoretical guarantees in several regimes and empirically is…
ADMM LP decoding of non-binary LDPC codes in
Xishuo Liu, Stark C. Draper
In this paper, we develop efficient decoders for non-binary low-density parity-check (LDPC) codes using the alternating direction method of multipliers (ADMM). We apply ADMM to two…
Unequal Message Protection: Asymptotic and Non-Asymptotic Tradeoffs
Yanina Y. Shkel, Vincent Y. F. Tan, Stark C. Draper
We study a form of unequal error protection that we term "unequal message protection" (UMP). The message set of a UMP code is a union of disjoint message classes. Each class ha…
SleepScale: Runtime Joint Speed Scaling and Sleep States Management for Power Efficient Data Centers
Yanpei Liu, Stark C. Draper, Nam Sung Kim
Power consumption in data centers has been growing significantly in recent years. To reduce power, servers are being equipped with increasingly sophisticated power management mecha…
