	1	Construction of Type-II QC LDPC Codes Based on Perfect Cyclic Difference Set显示文摘Quasi-cyclic(QC) Low-density paritycheck(LDPC) codes are constructed from combination of weight-0(null matrix) and Weight-2(W2) Circulant matrix(CM), which can be seen as a special case of the general type-II QC LDPC codes. The shift matrix of the codes is built on the basis of one integer sequence, called perfect Cyclic difference set(CDS), which guarantees the girth of the code at least six. Simulation results show that the codes can perform well in comparison with a variety of other LDPC codes. They have excellent error floor and decoding convergence characteristics.

	2	Constructions of QC LDPC codes based on integer sequences显示文摘Based on difference sequence and Hoey sequence,three types of(2,F)and(3,F)quasi cyclic(QC)low-density parity-check(LDPC)codes are constructed.All 4-cycles and even 6-cycles are removed in the Tanner graph,and the girth is not less than six.The decoding complexity as well as extension to irregular case is analyzed.Simulation results show that in AWGN and Rayleigh fading channels,the codes can achieve the same error performance as their counterpart PEG codes,and outperform the corresponding MacKay codes and array codes.
