摘要

超宽带基带系统采用M元双正交键控（MBOK）调制

该调制方式在提高数据传输速率时无需大幅度增加带宽。为了提高数据传输的可靠性

文章在编码前加入一种块交织器

该设计的独特之处在于采用两块RAM交替进行读写操作

使交织器的延时最小化。用VHDL语言编程

在FPGA上用QUARTUSⅡ软件进行仿真

结果证明

在MBOK系统中加入交织器后可以交织随机化突发错误

便于系统纠错功能的实现。

Abstract

MBOK modulation is introduced in the UWB baseband system

for which no substantial bandwidth increase is necessary when the data transmission rate is to be boosted.In order to improve the data transmission reliability

a block interleaver is added before the data coding.What is unique to this design is that two pieces of RAM registers are employed for alternative reading and writing so as to minimize the time delay of the interleaver.Besides

programming is implemented with VHDL and simulations performed on FPGA with QUARTUS II.The result shows that when the interleaver is added to the MBOK system

burst errors are interleaved for easier error corrections of the system.
