Comparison of Terminated and Tailbiting Spatially Coupled LDPC Codes With Optimized Bit Mapping for PM-64-QAM

Paper i proceeding, 2014

We optimize the allocation of coded bits to modulation bits for spatially coupled low-density parity-check (SC-LDPC) codes and PM-64-QAM. Tailbiting SC-LDPC codes are shown to offer a similar gap to capacity as their terminated counterparts, at a lower FEC overhead.
