Characterizing the Rate Region of the (4,3,3) Exact-Repair Regenerating Codes
Chao Tian
Exact-repair regenerating codes are considered for the case (n,k,d)=(4,3,3), for which a complete characterization of the rate region is provided. This characterization answers in…
Distributed Data Storage Systems with Opportunistic Repair
Vaneet Aggarwal, Chao Tian, Vinay A. Vaishampayan +1
The reliability of erasure-coded distributed storage systems, as measured by the mean time to data loss (MTTDL), depends on the repair bandwidth of the code. Repair-efficient codes…
Rate Region of the (4,3,3) Exact-Repair Regenerating Codes
Chao Tian
Exact-repair regenerating codes are considered for the case (n,k,d)=(4,3,3), for which a complete characterization of the rate region is provided. This characterization answers in…
Exact-Repair Regenerating Codes Via Layered Erasure Correction and Block Designs
Chao Tian, Vaneet Aggarwal, Vinay A. Vaishampayan
A new class of exact-repair regenerating codes is constructed by combining two layers of erasure correction codes together with combinatorial block designs, e.g., Steiner systems,…
Gaussian State Amplification with Noisy State Observations
Bernd Bandemer, Chao Tian, Shlomo Shamai
The problem of simultaneous message transmission and state amplification in a Gaussian channel with additive Gaussian state is studied when the sender has imperfect noncausal knowl…
