摘要

超宽带(UWB)通信采用非常短的脉冲，具有不同的调制方式，从而为高数据速率链路提供极宽带频谱。这些光谱是扩频运算和脉冲形状的函数。提出了一种基于经典滤波器的脉冲频谱优化技术。然后考虑非理想脉冲特性，并推导出最小能量(最高频谱带宽)的最佳脉冲。其动机是表明滤波脉冲可以在直接基带UWB信号中实现高数据速率通信的显著频谱控制。

Pulse spectrum optimization for ultra-wideband communication

Ultra-wideband (UWB) communications employ very short pulses with different modulation that result in extremely wideband spectra for high data-rate links. These spectra are a function of both the spreading operation as well as the pulse shapes. We propose a pulse spectrum optimization technique based on classical filters. Non-ideal impulse characteristics are then considered and the optimum pulse derived for either minimal energy (highest spectral bandwidth). The motivation is to show that filtered pulses can achieve significant spectral control in direct baseband UWB signals for high data-rate communications.
