摘要

在数字通信中，准确模拟和复制发射机和接收机之间的信道效应对于评估它们对传输数据的影响至关重要。因此，获得实时信道仿真器对于开发电信系统至关重要。本文介绍了一种基于 FPGA 的可配置、灵活且高性能的信道仿真器，它支持多种信道模型，包括多普勒、AWGN 和多路径衰落。我们探讨了组件的位宽精度，并提出了质量和资源利用率之间的权衡。我们的探索表明，在保持信道效应精度并以 500 Msps 的高吞吐量运行的同时，各种资源节省了 25% 至 45%。

Real-FlexE: Real-time Flexible channel Emulator

In digital communications, accurately modeling and replicating the channel effects between a transmitter and receiver is essential to assess their impact on transmitted data. Access to a real-time channel emulator is therefore crucial in the development of telecommunication systems. This paper presents a configurable, flexible, and high-performance FPGA-based channel emulator that supports multiple channel models, including Doppler, AWGN, and multi-path Fading. We explore bit-width precision in the components and present trade-offs between quality and resource utilization. Our exploration demonstrates
