Design of Compatibility Interleaver in Ultra Wide Band Wireless Communication System

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.
