摘　　要：在通信系统中,交织器的选择具有重要的地位。首先研究了多项式交织器,分析了其设计原则,其可以用置换多项式表示,接收端通过逆多项式解交织,从而节约了发送和接收时间,减小了传输压力。然后通过星座点分布图比较了其与S交织器的异同。最后将两种交织器应用在LTE和重叠编码复用平台上,通过仿真,综合各方面因素,验证了多项式交织器性能优于S交织器。In communication system,it is important to choose the kinds of interleaver.First,the polynomial interleaver is studied and the design principle of its coefficients is analyzed.It could be expressed by polynomial,and inverse polynomial is applied by receiver to carring out de-interleaving,thus saving the sending and receiving time and reducing the pressure of transmission.Then its comparison with S-interleaver is intensively studied.Finally the two interleavers are applied on LTE（Long Term Evolution） and OVCDM（Overlapped Code Division Multiplexing） platform.The simulation indicates that the polynomial interleaver is superior to s-interleaver.
