Performance analysis on LDPC-Coded systems over quasi-static (MIMO) fading channels
In this paper, we derive closed form upper bounds on the error probability of low-density parity-check (LDPC) coded modulation schemes operating on quasi-static fading channels. Th...

Unified decoder architecture for LDPC/turbo codes
Low-density parity-check (LDPC) codes on par with convolutional turbo codes (CTC) are two of the most powerful error correction codes known to perform very close to the Shannon li...

Product code error protection of packetized multimedia bitstreams
Sherwood and Zeger proposed a source-channel coding system where the source code is an embedded bitstream and the channel code is a product code such that each row code is a conca...

Better extractors for better codes?
We present an explicit construction of codes that can be list decoded from a fraction (1 - ) of errors in sub-exponential time and which have rate / logO(1) (1/). This comes close...

Constrained systems with unconstrained positions
We develop methods for analyzing and constructing combined modulation/error-correctiong codes (ECC codes), in particular codes that employ some form of reversed concatenation and w...
