基于VC的LTE4G通信modem软件仿真平台的搭建

摘要

This paper describes the simulation platform to build 4G wireless describes the architecture and processing systems, and describes the relevant module, as well as the interaction between modules. Focuses on the inter-module communication media-using the ring buffer, so that data can be securely transmitted between the modules. The ring buffer has a small footprint, easy to manage, etc., can be widely applied to other common platforms. Also, the simulation platform using C language development, programming is simple and easy to develop a successor. And platform portability, and easy migration development on different operating systems. At the same time, the simulation platform uses a modular design, with good scalability, hardware logic by modifying the code stub code, can be used on different chip development platform.%文中阐述了4G无线仿真平台的搭建，描述了系统的架构和处理流程，并介绍了相关模块，以及模块间的交互过程。重点阐述了模块间通信的介质-环形缓冲区的使用，使得数据能够在模块间安全的传递。该环形缓冲区具有占用空间小，易于管理等优点，能够广泛应用于其它通用平台。并且，该仿真平台使用C语言开发，编程简洁，方便后继开发；且平台的可移植性好，方便在不同操作系统上移植开发。同时，该仿真平台使用模块化设计，具有良好的扩展性，通过修改代码硬件逻辑的桩代码，可以使用在不同的芯片开发平台上。
