提出了一种利用超宽带（UWB）超小型无线互连方案的新概念。该概念使用PC塔机箱作为模型环境，其中使用两种不同类型的天线进行了信道测量活动。对天线的不同位置进行了Ricean K因子分析，以确定信道的多径行为以及信道容量。假设信噪比为25 dB，使用其中一个天线的整个UWB频段可以实现近6 Gbit/s的平均最大信道容量。这项工作支持了一项建议，即用于在PC情况下通信不同设备的高容量UWB无线互连方案可用于取代有线互连，提供无线背板系统。
A novel concept of the use of an ultra-wide bandwidth (UWB) ultra-small-scale wireless interconnect scheme inside an electrically small enclosure is proposed. The concept is presented using a PC tower case as a model environment in which a channel measurement campaign has been made with two different types of antennas. Ricean K factor analysis was conducted for different positions of the antennas to identify the multipath behaviour of the channel, as well as channel capacity. An average maximum channel capacity of almost 6 Gbit/s is achieved using the whole UWB band for one of the antennas, assuming a signal-to-noise ratio of 25 dB. This work supports the proposal that a high-capacity UWB wireless interconnect scheme for communicating different devices within a PC case scenario may be used to replace wired interconnections, providing a wireless backplane system.
