基于交织多址(IDMA)系统的因子图表示，提出了交织器设计准则。提出了一种适合于多用户交织器方向图设计的渐进边缘生长(PEG)算法。仿真结果表明，所设计的交织器性能优于随机交织器，特别是在用户数相对较大的情况下。
Based on factor graph representation of IDMA (interleave division multiple-access) systems, an interleaver design criterion is proposed. The progressive edge growth (PEG) algorithm proposed for LDPC codes is adapted to multi-user interleavers pattern design. Simulation results show that the designed interleavers perform over random interleavers especially when the number of users is relative large.
