摘要 文章首先概述了产生超宽通道的行业背景,接着介绍了产生超宽通道的两种主要方式;分别阐述了OFDM(正交频分复用)调制方式和Nyquist(奈奎斯特)滤波方式的基本原理和产生途径,分析了这两种方式的优劣特点并进行了比较;最后综述了两种方式的研究现状及今后展望。 This paper first reviews the industrial background of realizing ultra-wideband transmission and introduces two main approaches for its realization： OFDM modulation and Nyquist filtering and their fundamental principles. It then analyzes and compares their advantages and disadvantages. Finally, it summarizes the present conditions of their researches and looks for- ward to their prospects.
