Architectures for ASIC implementations of low-density parity-check convolutional encoders and decoders
— Low-Density Parity-Check Convolutional Codes (LDPC-CCs) are an attractive alternative to their block-oriented counterparts, LDPC-BCs. In this paper, we introduce these codes an...

Optimal delayed decoding of predictively encoded sources
Predictive coding eliminates redundancy due to correlations between the current and past signal samples, so that only the innovation, or prediction residual, needs to be encoded. ...

Multi-layer parallel decoding algorithm and vlsi architecture for quasi-cyclic LDPC codes
—We propose a multi-layer parallel decoding algorithm and VLSI architecture for decoding of structured quasi-cyclic low-density parity-check codes. In the conventional layered de...
