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，重点掌握卷积编码、块交织和码扩展等相关编码技术，并能将这些技术应用实际系统设计-MATLAB software access channel part of the design, analysis, simulation and verification of each module. The aim is to graduate design work to be familiar with modern wireless communication systems constitute the basic working principle, focus on mastering the convolutional coding, block interleaving and code extension-related coding techniques, and can these technologies in actual system design
