摘要：In indoor environments, the throughput of ultrawideband (UWB) systems depends much on the channel condition. In this paper, a two-stage adaptive UWB transmission scheme is proposed to improve the throughput, where deep-learning is used to realize channel classification. In the first stage, the channel type is identified by using a newly designed channel classifier which i s based o n deep neural networks (DNN) and trained with IEEE 802.15.3a channel model data set. In the second stage, the transmission rate is adjusted to match the channel condition and thus improve the throughput. To gain accurate channel classification, an ensemble decision layer is used jointly with the DNN-based channel classifier. Simulation results show that attractive classification accuracy c an b e a chieved by using the proposed channel classifer and the throughput of UWB system can be improved effectively. © 2019 IEEE.
