基于FPGA技术的DSC-UWB发射系统

A FPGA-based DSC-UWB transmitter

超宽带(UWB)无线通信技术是一种利用极窄脉冲进行通信的新技术,因其具有低功耗,良好的抗干扰和抗多径的能力以及系统高容量的特点,特别适用于军事隐蔽通信和室内密集多径环境下的高速数据接入,已成为一种极具竞争力的短距离无线通信方式。

Ultra-Wide Band (UWB) is a new wireless communication technology by using nano-second width pulse.More comprehensive attention has been taken to it because of its low power consumption,good ability of anti-interference and anti-multiple-path and high system cability. In this paper, the Direct-Sequence Phase Coded Ultra-Wide Band System is introduced,and a transmitter design based on FPGA is given.The results of simulation and circuit experiment show the feasibility of the design.
