Construction of Regular Quasi-Cyclic Protograph LDPC codes based on Vandermonde Matrices
Abstract— In this contribution, we investigate the attainable performance of quasi-cyclic (QC) protograph Low-Density Parity-Check (LDPC) codes for transmission over both Additiv...

Iterative Decoding of Concatenated Channel Coding and Trellis Shaping Based on Markov Model
—The trellis shaping (TS) is an effective technique not only for average power reduction of high-order QAM signals, but also for peak power reduction of band-limited single-carri...

Defragmenting DHT-based Distributed File Systems
Existing DHT-based file systems use consistent hashing to assign file blocks to random machines. As a result, a user task accessing an entire file or multiple files needs to r...

Adaptive Spatial and Transform Domain FGS Coding
In inter-picture coding, block-based frequency transform is usually carried out on the predicted errors for each interblock to remove the spatial correlation among them. However, ...
