ecent advances in electrical engineering and computer science, esp ecially in micro- electro-mechanical systems (MEMS), very-large-scale integration (VLSI) and op erating system theory, have made wireless sensor network (WSN) technologies an imp ortant and promising research area. As the circuitry b ecame smaller and cheap er, the idea of co op eratively sensing physical or environmental conditions, such as magnetic eld intensity, temp erature, light intensity, sound, vibration, pressure, motion or p ollutants with the help of a network of sensor no des has b ecome feasible.

理论知识是用来指导具体实践的。本文在深刻理解通信系统理论的基础上利用 MATLAB 强大的仿真功能，设计了许多具体的通信系统仿真模型。在仿真模型设计过程中，本文对模型设计的目的、具体的结构组成、仿真流程以及仿真结果都给出了具体详实的分析和说明。(Theoretical knowledge is used to guide the specific practice. In this paper, a deep understanding of the theory of communication systems using MATLAB based on the powerful simulation function, the design of a number of specific communication system simulation model. In the simulation model of the design process, this article is designed on the model, the specific structural components, simulation and flow simulation results are given specific and detailed analysis and description.)

选取CDMA通信系统中的接入信道部分进行仿真与分析。首先，通过学习相应的理论知识，熟悉接入信道实现的过程，对每一步的原理有了较深的理解，同时，也对MATALB软件进行熟悉和了解，对MATLAB软件中的SIMULINK部分及其内部的CDMA模块用法和参数设置进行熟悉，然后运用MATLAB软件对接入信道部分进行设计，并逐步地对各个模块进行分析、仿真与验证。目的是通过毕业设计工作熟悉现代无线通信系统的基本构成与基本工作原理-CDMA (communication system to select the access channel simulation and analysis of parts. First of all, by learning the theory of knowledge, familiar with the access channel to achieve the process, with each step deeper understanding of the principle, at the same time, but also familiar with the software MATALB and understanding of the MATLAB software and its internal part of the SIMULINK use of the CDMA module and parameter settings are familiar with, and then use MATLAB software to access parts of the design of channel and step by step analysis of each module, simulation and verification. The purpose of design work through graduate familiar with the modern wireless communication systems constitute the basic and fundamental principle,)
