长度为N的扩展交织器是基于在设计约束下不替换从1到N的N个整数的随机选择的半随机交织器。本文基于交织器在整个 Turbo 码错误事件距离中的作用，将扩展交织器设计方法扩展到多个错误事件。该扩展有助于解释为什么扩展交织器被专门设计为半随机的。仿真结果显示了符号交织并行级联网格编码调制 (PCTCM) 方案所实现的性能。
A spread interleaver of length N is a semi-random interleaver based on the random selection without replacement of N integers from 1 to N under a design constraint. This paper extends the spread-interleaver design method to multiple error events, based on the interleaver's role in overall turbo code error event distances. The extension helps to explain why the spread interleaver is specifically designed to be semi-random. Simulation results show the performance achieved for a symbol-interleaved parallel concatenated trellis coded modulation (PCTCM) scheme.
