WINNER II D6.13.12 v1.0Additionally, a parity check matrix for R = 1/3 BLDPCC is also provided, but this code is not ratecompatiblewith other rates at the moment. For the DBTC the following compatible code rates can beobtained through puncturing:⎧12 1 4 2 3 4 6 ⎫R = ⎨ , , , , , , , ⎬(5.2)⎩35 2 7 3 4 5 7 ⎭Both the BLDPCC and DBTC have their advantages and disadvantages, but their performance vs.decoding complexity is not a sufficient metric to take the final choice, since more implementation aspectswould need to be taken into account. Further complexity comparison can be found in appendix F.2 from[WIND210]. Besides, Table 5.1 from [WIND210] summarises the proposed FEC techniques with respectto their performance, memory requirements, decoding complexity and maturity 3 .Table 5.1: Comparison of the most promising FEC techniques [WIND210]CC 4 DBTC BLDPCCPerformance 5 Short blocks -
