摘　　要：本文介绍了一种基于千兆以太网的软件无线电前端设计实现。首先给出主要硬件构成,然后重点讨论了关键模块的设计,最后介绍测试方法。测试结果表明设计方案具有高速、大宽带、大动态范围的特性,且能够应用分布式等技术,使得软件无线电系统更接近理想目标。In this paper, an approach that designs high speed transmitting for SDR front-end based on gigabit Ethernet is introduced. We explain the hardware and the main module of the system in FPGA, as well as its test result. It is found that this scheme always not only provides the performance of high speed, large bandwidth and better dynamic spectrum, but also directly applies in distributed wireless communication system.
