基于RFID技术的人员定位系统设计
摘要
随着通信系统复杂性的增加,传统的分析设计方法已经不能适应发展的需要。
如果每次都直接用真实系统进行实验,不仅耗资昂贵,费工费时,有时甚至难于找到
问题症结所在。因此,解决上述问题的有效方法是采用计算机仿真技术和利用计算机
的高速运算处理能力。
本文首先简要介绍了数字通信系统一些基本原理,以及脉冲编码调制和基带传输
中所涉及到的原理、框图。MATLAB是MATHWORKS公司推出的一套高效率的数值计
算和可视化软件,它集数值分析、矩阵运算·信号处理、和图形显示于一体,构成了
一个方便的、界面友好的用户环境。
在随后的两章中,更深入的阐述了脉冲编码调制和基带传输的一些基本原理、公
式,以及它们在MATLAB中的实现,并注重仿真工程应用的系统化,均严格按照各
种理论系统进行仿真过程的设计,使所有工程内容都可以找到理论根源。
关键词:MATLAB脉冲编码调制基带传输仿真

With the increase munication plexity, traditional analysis design
method can not fit in with the needs of development. if the experiment is carried on the true system directly each time, which not only costs expensively, takes a lot of time,sometimes even it is difficult to find the very crux of the question. Therefore,the effective method is to adopt the emulation technology of puter. So that puter's ability of high-putation can be used mostly.
In this article the basic principle of munication system and some principles and graphs of pulse coding modulation as well as baseband transmission have been introduced at first. MATLAB is a suit of high efficiency and visual software which has developed by pany. It collects data analysis, matrix operation, signal
process and graph to build a convenient and interface-friendly environment.
Thereafter, the basic principle, formula of pulse coding modulation and baseband transmission as well as how to achieve them at MATLAB have been expounded deeply. Especially pay attention to the systematize of using the emulation technology. It do design
of emulation all according to each theory system, every project content could find the
SOURCE OF THEORY.
