| 摘 要： | 为了客观评价和鉴定各种通信设备,需要营造逼真的宽频带、高密度、多样式的电磁信号环境。基于数据抽取和插值理论,提出了一种并行直接数字合成(DDS)技术。基于并行DDS技术,研究了宽带通信信号模拟方法,可以用来在宽频带范围内模拟复杂的通信信号环境。利用高性能复杂可编程门阵列(FPGA)和高速数模转换器(DAC)实现了16路并行DDS,可直接在射频频段产生各种样式的通信信号。

| Abstract: | In order to evaluate all kinds of communication equipment, a kind of realistic wide band, high density, versatile electromagnetic signal environment should be built up. Based on the data extraction and interpolation theory, a parallel direct digital synthesis (DDS) technology was proposed. Based on this parallel DDS technology, a wide band communication signal simulation method was researched, which could be used to simulate the complicated communication signal environment in the wide band spectrum. A 16 channel parallel DDS was implemented by using the high performance FPGA and high speed DAC, which could produce various types of communication signals in the radio frequency band. |
