多输入多输出(MIMO)技术具有显著提高无线通信系统数据速率和频谱效率的潜力。即使对发送和接收算法的设计进行了广泛的研究，也几乎不知道在真实的无线信道上实际可以实现多少预测增益。在本文中，我们提出了一种MIMO试验台，它使得宽带信道的MIMO收发信机能够快速成型。这样的原型提供了从MIMO算法可实现的增益的实验量化。该试验台设计允许基带处理和射频上/下变频的实时操作。试验台组件的选择是为了最大限度地实现研究目的的灵活性，包括对所有子系统的监控。除了讨论试验台的设计外，我们还给出了两个无线系统的实现。第一种是基于IEEE 802.11b的扩频系统。第二种是对Alamti的发射分集方案的实现。
Multiple input multiple output (MIMO) techniques hold the potential of dramatically increasing the data rates and spectral efficiency of wireless communications systems. Even with extensive research on the design of transmission and reception algorithms, little is known as to how much of the predicted gains are actually achievable on real wireless channels. In this paper, we present a MIMO testbed, which enables the rapid prototyping of MIMO transceivers for wideband channels. Such prototypes provide experimental quantification of achievable gains from MIMO algorithms. The testbed design allows real-time operation of baseband processing and RF up/down-conversion. The choice of testbed components is made to allow maximum, flexibility for research purposes, including monitoring and control of all subsystems. In addition to discussing the testbed's design, we present the implementation of two wireless systems. The first is a spread-spectrum system based on IEEE 802.11b. The second is an implementation of Alamouti's transmit diversity scheme.
