一种基于数字重采样的多载波调制方法
Multi-carrier Modulation Based on Digital Re-sampling
摘要
Abstract
This paper proposes a multi-carrier modulation method based on digital re-sampling.This method firstly shifts baseband modulation signals of different rates to the same sampling rate;then according to the allocated frequency,digital upconversion and multiplexing are conducted;finally,multiplexed signals are sent to a special chip for IF digital modulation.Compared with traditional IF-based multiplexing modulation,the method introduced in the paper has a better channel consistency and is easy to be implemented.关键词
