摘要：
This letter presents an approach to the construction of multiple-rate quasi-cyclic (QC) low-density parity-check (LDPC) codes based on hyperplanes (mu-flats) of two different dimensions in Euclidean geometries The codes constructed with this method have the same code length multiple-rate and large stopping sets while maintaining the same basic hardware architecture The code performance is investigated in terms of the bit error rate (B ER) and complied with those of the LDPC codes which are proposed in IEEE 802 16e standard. Simulation results show that Our codes perform very well and have low error floors over the AWGN channel.
