摘　　要：同频同时全双工技术是一种有效提高频谱效率的新型无线通信技术,而目前国内外尚缺少对于全双工系统信道建模以及组网技术的研究。给出了同频同时全双工系统级仿真平台的体系框架,描述了全双工系统级仿真平台的主要模块的功能及实现方法。分析了多种同频同时全双工系统的自干扰消除技术并建立了自干扰消除模型和传输信道模型,基于C语言搭建了同频同时全双工系统级仿真平台,为全双工系统的组网研究奠定了基础。仿真结果验证了同频同时全双工系统级仿真平台的有效性,并给出了同频同时全双工系统的频谱效率及其主要影响因素。Full duplex communication is a new wireless communicating technology for improving the spectrum efficiency substantially. Few researches study full duplex networking technology now nationally and internationally. The architecture and implementation approach of full duplex communication system are introduced to describe the main model and functions of the platform in detail. After analyzing different kinds of self-interference cancellation technology, the self-interference cancellation module and channel model of full duplex system in the platform is built based on C language, which lays a foundation for prospective full duplex networking technology. Simulation results verify the platform ＂s effectiveness, and present the spectrum efficiency and its major factors.
