【摘要】 文中从脉冲噪声模型的特点出发,主要研究了超宽带系统在脉冲噪声干扰下的系统性能,提出了一种针对脉冲噪声环境下的接收机结构,并推导分析了该接收机的BER性能。仿真结果表明,脉冲指数对超宽带系统BER性能有较大影响,接收机BER性能由于受到脉冲噪声的影响有一定的恶化,因此该接收机实现的BER性能优于常规接收机。更多还原

【Abstract】 This paper discusses ultra-wideband(UWB) system performance in complex impulse noise channel and presents a new structure of UWB receiver which adapts to the channel.In this paper,the formulas for analyzing bit error rate(BER) are given.Simulations show that impulse exponent has an important effect on the BER performance of UWB system,which will be deteriorated by impulse noise.So,new-discussed receiver has better BER performance than traditional receiver.更多还原
