摘要: 设计一种应用于超宽带(UWB)无线通信系统的交织器,采用双端口随机存取存储器结合地址发生器的结构,实现多波段正交频分复用和双载波正交频分复用2种标准下比特交织的兼容。相比只适用于单一标准的交织器,该交织器在查找表数目增加4.5%、寄存器数目增加1.8%的情况下,工作主时钟达到132 MHz,数据吞吐率达到最大1.42 Gb/s,满足UWB系统要求。

Abstract: This paper designs a interleaver which is used in Ultra Wide Band(UWB) system. The interleaver is based on the structure of two port Random Access Memory(RAM) and address generator, it can be compatible with standards of Multi Band-Orthogonal Frequency Division Multiplexing(MB-OFDM) and Dual Carrier-Orthogonal Frequency Division Multiplexing(DC-OFDM). To compare with the interleaver applied to only one standard, this interleaver just increase 4.5% and the registers increase 1.8%. The main clock frequency is 132 MHz and the max throughput is 1.42 Gb/s, and it meets the requirement of UWB system.
