Design of Efficiently-Encodable Generalized LDPC Codes

We propose two classes of efficiently-encodable GLDPC (EE-GLDPC) codes by generalizing the ideas of IRA and EERC codes. These GLDPC codes have performance as good as ordinary GLDPC codes. Moreover, another advantage of these EE-GLDPC codes is that they are naturally suitable for puncturing. Simulation shows that, at code length around 600, the punctured EE-GLDPC codes can outperform optimized irregular LDPC codes by 0.4-0.5 dB at BER=10^-6, making them good candidates when designing error correcting codes at short-to-medium code lengths.
