摘要

超宽带(UWB)脉冲无线电使用非常短的脉冲，满足美国联邦通信委员会(FCC)发布的频谱掩模。此外，为了消除多址应用中的码间干扰，这些脉冲应该是正交的。产生这些脉冲的一种技术是整形。整形是通过称为脉冲整形器的带通滤波器实现的。最流行的符合fcc的正交脉冲利用长球面波函数。在本文中，我们提出了模拟脉冲整形器，其脉冲响应近似于最小二乘意义上的长球面脉冲。此外，我们提供了fcc兼容的传递函数，产生高度正交的脉冲响应。

Prolate-spheroidal UWB pulse shapers with highly orthogonal impulse responses

Ultra-wideband (UWB) impulse radio uses very short pulses that meet spectral mask released by Federal Communications Commission (FCC). In addition, to eliminate inter-symbol interference in the multiple-access applications, these pulses should be orthogonal. One technique to generate these pulses is shaping. The shaping is realized with bandpass filters called pulse shapers. The most popular FCC-compliant orthogonal pulses utilize prolate spheroidal wave functions. In this paper, we propose analog pulse shapers whose impulse responses approximate the prolate spheroidal pulses in the least squares sense. Furthermore, we provide their FCC-compliant transfer functions that yield highly orthogonal impulse responses.
