摘要

自首次发布以来，WiFi在提供无线局域网方面取得了巨大成功。不断发展的IEEE 802.11标准不断添加新功能，以跟上移动设备数量增加和物联网（IoT）应用增长的趋势。不幸的是，社区中缺乏开源的IEEE 802.11测试平台限制了这些新特性的开发和性能评估。基于现有流行的基于IEEE 802.11/a/g/p标准的单用户单流传输开源软件定义无线电（SDR）包，本文提出了基于802.11n和802.11ac标准的单用户和多用户多输入多输出（MIMO）传输开源包GR-WiFi。GR-WiFi的独特特点包括支持单个或多个用户的并行数据流，以及兼容的前置处理，允许传统、高吞吐量（HT）和非常高吞吐量（VHT）流量共存。GR-WiFi的性能通过广泛的模拟和现实世界的实验来评估。

GR-WiFi: A GNU radio based WiFi platform with single-user and multi-user MIMO capability

Since its first release, WiFi has been highly successful in providing wireless local area networks. The ever-evolving IEEE 802.11 standards continue to add new features to keep up with the trend of increasing numbers of mobile devices and the growth of Internet of Things (IoT) applications. Unfortunately, the lack of open-source IEEE 802.11 testbeds in the community limits the development and performance evaluation of those new features. Motivated by an existing popular open-source software-defined radio (SDR) package for single-user single-stream transmission based on the IEEE 802.11/a/g/p standard, in this paper we present GR-WiFi, an open-source package for single-user and multi-user multi-input multi-output (MIMO) transmissions based on 802.11n and 802.11ac standards. The distinct features of GR-WiFi include the support of parallel data streams to single or multiple users, and the compatible preamble processing to allow the co-existence of conventional, high-throughput (HT) and very-high-throughput (VHT) traffics. The performance of GR-WiFi is evaluated through both extensive simulation and real-world experiments.
