The punctured NB-LDPC codes have been used in a simulated model of the transmission system. The link level performance has been evaluated in terms of spectral efficiency, codeword error rate and average number of retransmissions. The NB-LDPC codes can be easily and effective implemented with different methods of the retransmission needed if correct decoding of a codeword failed. Here the Optimal Symbol Selection method is proposed as a Chase Combining technique. }, journal = {International Journal of Electronics and Communication Engineering}, volume = {4}, number = {6}, year = {2010}, pages = {964 - 969}, ee = {https://publications.waset.org/pdf/5228}, url = {https://publications.waset.org/vol/42}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 42, 2010}, }
