dc.description.abstract | Wireless communications have attracted great
interest from the industry due to its lower cost and the possibility
of enabling new use cases. The new use cases are commonly
related to mobile robotics, such as Unmanned Aerial Vehicles.
The design of wireless systems for these use cases requires deep
knowledge of the channel behavior. However, the weight and
size of full channel sounders exceed the payload of most mobile
robots. In addition, full channel sounders usually require wired
time synchronization. Hence, channel measurements in these
scenarios are constrained to use limited channel sounders, which
can only measure some specific parameters (frame error rate,
channel attenuation, etc.). In this paper, we present the design
and implementation of a portable 802.11-based channel sounder
combined with a sub-nanosecond wireless time synchronization
algorithm. Thanks to the wireless time synchronization, the
channel sounder can be used to periodically take complex
baseband Channel Impulse Response samples synchronized to
absolute time. From these samples, relevant channel parameters
can be extracted, including the Power Delay Profile, Doppler
spectrum, and channel delay. The verification of the channel
sounder through a wireless channel emulator confirms its
feasibility for mobile robotics applications. | |
