超宽带通信系统误码率的分析与仿真

Analysis and Simulation of BER in UWB Communication Systems

超宽带通信是一种通过高斯单周期窄脉冲序列实现高速信息传输的无线脉冲通信技术,该技术拥有传统技术所不具备的性能特点和巨大的开发潜力,但是要完全实现技术上仍存在难度。文章主要讨论了在AWGN信道下,推导出非最佳接收条件下系统误比特率与通信环境、互相关模板脉冲之间的关系,为超宽带通信试验系统的设计实现奠定了理论基础。

UWBCommunication is one kind of wireless pulse communication technology, which realizes high-speed information transmission through the narrow single-cycle gaussian pulse sequence. Thus the technology has the performance characteristics and enormous development potential the traditional technologies would not have. However, it is still difficult to fully realize this technology. This paper mainly discusses the AWGN channel, derives system and communication environment under the condition of non-best receiver, cross correlation relationship between the template pulses, lays a theoretical basis for design and implementation of ultra-wideband communication test system.
