摘　　要：针对OFDM基带系统的软件仿真和硬件验证,提出并设计了一种基于FPGA的OFDM基带系统软硬件联合验证方案。在该方案中,基带系统由上位机的软件基带部分和FPGA的硬件基带部分组成。两者之间的数据连接由基于以太网的UDP协议实现,从而在验证平台上实现了完整的基带系统。应用实例表明,在所提出的基带系统验证平台中,软件仿真可以运行于实际信道,硬件验证的结果可以得到灵活的实时处理。因此该平台为基带系统的设计提供了从算法研究到硬件实现的统一测试环境,有效提高了设计效率。In order to simulate the software implementation and verify the hardware implementation of a baseband OFDM system, an FPGA-based software/hardware co-verification scheme is proposed. The system is divided into two partitions implemented by software and hardware, respectively. UDP is used for data transmission between these two partitions, and hence makes a complete baseband system. With the proposed testbed, the software simulation is running over real wireless channels, and the hardware implemental results can be flexibly processed in real time. Therefore, the testbed provides a uniform environment for the design process of the baseband OFDM system from algorithm to implementation, and enhance the design efficiency.
