摘要:
how to enhance the intelligence for wireless communication networks? one promising direction is to fuse more environmental information to the network, such as building radio maps. radio map is a data model that describes the wireless communication quality between any transmitter and receiver location pair. the technology has been successfully used for network planning, spectrum management, and fingerprint localization for over 20 years. however, conventional radio map techniques were limited to the case where the transmitter locations are fixed and the maps are usually 2-d by varying the horizontal receiver location only. such a radio map is blind to the actual geographic environment, limiting the choice of control actions for adapting the network to the environment. however, allowing the transmitter location to vary is very challenging, because it effectively raises the radio map dimension from 2-d to 6-d. consequently, classical methods for radio map sensing and construction will fail due to the exponentially increasing cost for collecting huge amount of measurement data.
in this talk, we start from classical applications of radio maps and the approaches to build them. then, we explore two recent research directions: first, we establish new models and methods for sensing and constructing a 6-d radio map and a hidden environment map simultaneously; the environment map describes locations and shapes of buildings and vegetation in the neighborhood of the communication network. second, we develop sparse signal processing techniques to construct a 2-d radio map from small samples, and demonstrate its advantage in received-signal-strength (rss) based localization in harsh environment.
