Efficient Quantum Stabilizer Codes: LDPC and LDPC-Convolutional Constructions

IEEE Transactions on Information Theory, 2010
Existing quantum stabilizer codes constructed from the classic binary codes exclusively belong to the special subclass of Calderbank-Shor-Steane (CSS) codes. This paper fills in the gap by proposing five systematic constructions for non-CSS stabilizer codes, the first four of which are based on classic binary quasi-cyclic low-density parity-check (LDPC)

The rate of regular LDPC codes

IEEE International Symposium on Information Theory, 2003. Proceedings., 2003
Summary: We find the rate of a typical code from the regular low-density parity-check (LDPC) ensemble. We then show that the rate of a code from the ensemble converges to the design rate in quadratic mean and almost surely.

LDPC Decoding on the Intel SCC

2012 20th Euromicro International Conference on Parallel, Distributed and Network-based Processing, 2012
Low-Density Parity-Check (LDPC) codes are powerful error correcting codes used today in communication standards such as DVB-S2 and WiMAX to transmit data inside noisy channels with high error probability. LDPC decoding is computationally demanding and requires irregular accesses to memory which makes it suitable for parallelization.

Design of optimal LDPC code for the system of GMSK concatenated with LDPC codes

2011 2nd International Conference on Control, Instrumentation and Automation (ICCIA), 2011
This paper mainly concerns on the continuous phase modulation system of GMSK concatenated with LDPC codes. Decomposing GMSK signal into differential coding and PAM modulating manner, we analyze the iterative demodulating and decoding principle and design optimal LDPC codes based on EXIT chart.

eIRA LDPC Codes on FPGA

IEEE Communications Letters, 2011
eIRA codes are iteratively decodable low-density parity-check (LDPC) codes. They not only offer superior performance to alternative approaches, but they allow linear-time encoding. Well-designed eIRA codes also achieve extremely low error-rate floors. In this letter, we successfully implement a common FPGA platform for eIRA codes.

On the design of LDPC codes for MSK

GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002
We investigate serial concatenation of low-density parity check (LDPC) codes and minimum shift keying (MSK) with iterative decoding. We show that the design of LDPC codes is crucially dependent on the realization of the MSK modulator. For MSK modulators with nonrecursive continuous phase encoders (CPEs), optimal codes for BPSK are optimal, whereas for ...

Improved reversible LDPC codes

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
We provide a thorough analysis for a class of iteratively encodable low-density parity-check codes. The iterative encoding technique is based upon the graphical representation of the code and allows the decoder circuit to also be used for encoding, thus saving circuit area.
