A Construction for Low Density Parity Check Convolutional Codes Based on Quasi-Cyclic Block Codes

A set of convolutional codes with low density parity check matrices is derived from a class of quasi-cyclic low density parity check block codes. Their performance when decoded using the belief propagation algorithm is investigated.

Intersected Low-density Parity-check and Convolutional Codes

We look at the intersection of convolutional codes with high rate low-density parity-check codes. Threshold values are obtained with EXIT charts. Simulations show a gain of 1.5dB over a standard deepspace code.

Low Density Parity Check Convolutional Codes Derived from Quasi-Cyclic Block Codes

Abstract Using algebraic techniques, one of the co-authors has designed a [155,64,20] low density parity check code based on permutation matrices. This code is quasi-cyclic by construction and hence admits a convolutional representation. A set of low density parity check convolutional codes is derived from this quasi-cyclic code and its generalizations. We investigate the performance of these c...

A New Construction for Low Density Parity Check Convolutional Codes

Low density parity check (LDPC) block codes have been shown to achieve near capacity performance for binary transmission over noisy channels. Block codes, however, require splitting the data to be transmitted into frames, which can be a disadvantage in some applications. Convolutional codes, on the other hand, have no such requirement, and are hence well suited for continuous transmission. In [...
