Based on the discussion of chapter two , chapter three gives the baseband transmission architecture of ofdm communication system 第三章在上一章讨论的基础上,给出了ofdm通信系统的基带传输结构。
Also designed this part of correspondences procedure process and procedure codes . the thesis takes a simple introduction about the data transmission on base band 论文对数据基带传输编码做了简单介绍,阐述了数字基带信号的码型选择的原则。
The main contributions of this dissertation include : introduce the basic concept and class of pcma and then set up the base band transmission model 本文承担的主要工作如下: 1 、介绍pcma技术的基本概念与分类,分析其原理,然后建立了系统的基带传输模型。
The signals of multi - channel sensor at measuring spot were processed and translated by signal encoding technology to fuse into a baseband signal and then the signal was transmitted directly or in frequency - hand mode 该方法利用信号编码技术对测控现场的多路传感器信号进行处理和变换,使其融合为一路基带信号后,或直接以基带传输或以频带传输。
The single dsp can transmit baseband signal to digital up converter and receive baseband sample signal from digital down converter through the control of interrupt signal at the same time . the stability and reliability of complete digital transmission system can be realized by this way 本文利用dsp的中断控制,在单片dsp内发送基带数字信号同时处理来自数字下变频器的基带数字信号,实现了稳定、可靠的全数字中频与基带传输系统。
