Abstract: A novel method to implement low-complexity Field Programmable Gate Array(FPGA) for (de)interleaver is proposed, which uses dual-proted memory of Xilinx FPGA. The consumption for resources to FPGA is reduced and the read-width is not necessarily equal to write-width. It is fitting to Multi-Bandwidth Orthogonal Frequency Division Multiplex(MB-OFDM) Ultra-Wide Bandwidth(UWB) systems. Experimental results show the numbers of occupied slices are reduced by 46% and 78% for interleaver and deinterleaver respectively.

摘要： 提出一种低复杂度的(解)交织器现场可编程门阵列实现方法，采用Xilinx FPGA自带的双端口存储器，能有效降低FPGA资源的消耗，且输入位宽和输出位宽无需相同，适用于多带正交频分复用超宽带系统。实验结果表明，系统所占用的slices数目对于交织器和解交织器来说分别降低了46%和78%。
