MIMOSigRef-SD

The MIMOSigRef-SD dataset was created with the goal to support the research community in the design and development of novel multiple-input multiple-ouotput (MIMO) transceiver architectures. It was recorded using software radios as transmitters and receivers, and a wireless channel emulator to facilitate a realistic representation of a variety of different channel environments and conditions. This dataset was also used in the study of an Automatic Modulation Classification (AMC) or also known as Automatic Modulation Identification (AMI) system design, which is one of the application domains supported by this dataset. The transmitters generate a wide variety of signal streams modulated using one of the following modulation schemes in a variety of different modulation orders:•M-QAM•MIL-STD-188-110 B/C standard-specific QAM•M-PSK•M-APSK•DVB-S2/S2X/SH standard-specific APSK •M-PAMEach modulation scheme was also generated in a variety of Spatial Diversity (SD) MIMO system configurations, ranging from 1x1 (SISO) through 4x4 MIMO. Each signal was exposed to one of 5 different channel environments, ranging from Butler to Vehicular-B, with a signal-to-noise ratio ranging from -20 up to +30 dB. This dataset provides all of the generated bit sequences, channel configurations, and received symbols. **Our near-term plan is to further expand this dataset by also providing coverage for Spatial Multiplexing.**

MIMOSigRef-SD数据集旨在为研究社区开展新型多输入多输出（Multiple-Input Multiple-Output, MIMO）收发机架构的设计与研发提供支撑。本数据集通过软件无线电作为收发设备，搭配无线信道仿真器进行采集，以真实复现多种不同的信道环境与条件。
该数据集还被用于自动调制分类（Automatic Modulation Classification, AMC，又称自动调制识别（Automatic Modulation Identification, AMI））系统设计的相关研究，这也是该数据集支持的应用领域之一。
发射机生成的各类信号流采用下述多种调制制式，并配合不同的调制阶数：
• M进制正交幅度调制（M-QAM）
• 符合MIL-STD-188-110 B/C标准的专用正交幅度调制
• M进制相移键控（M-PSK）
• M进制幅度相位移位键控（M-APSK）
• 符合DVB-S2/S2X/SH标准的专用幅度相位移位键控
• M-PAME
每种调制制式均在多种空间分集（Spatial Diversity, SD）MIMO系统配置下生成，配置范围涵盖从1x1（单输入单输出，Single-Input Single-Output, SISO）到4x4的MIMO系统。每个信号均会经过5种不同的信道环境之一，包括Butler信道至Vehicular-B信道，信噪比范围为-20 dB至+30 dB。
本数据集包含所有生成的比特序列、信道配置以及接收符号。我们的近期计划是进一步扩展该数据集，新增对空间复用（Spatial Multiplexing）的支持。
