Rate-compatible turbo product codes with non-symmetry block codes for DVB-RCS NG systems

Soft based linear block codes combined with linear modulation cannot obtain the coding gains by increasing iterations. In this paper, we propose rate-compatible turbo product codes with extended BCH codes by zero padding and shortening the row and/or column to adapt next generation (NG) DVB-RCS system. And also, in order to make various coding rates required on standard, we used different coding rates between row and column codes. At the bit error rate (BER) of 10⁻⁴ the performance is better around 1.5 [dB] ∼2 [dB] compared to soft based extended BCH codes at the same coding rates.
