Staircase and other structured linear-time encodable LDPC codes: analysis and design
Federica Garin, Giacomo Como, Fabio Fagnani · 2007
We consider a family of codes which can be seen both as a special kind of serial turbo codes and as LDPC codes having a parity check matrix which is partly random and partly structured. These codes are linear-time encodable, thanks to the turbo structure, and can be decoded as LDPC codes. We provide an ensemble analysis for the waterfall region, on the line of classical results for serial turbo codes, and we find some design parameters.
