This inherent property of the sampling distribution allows for a significant reduction in the number of samples used for message multiplication without impairing localization accuracy notably. Reducing the number of samples, in turn, enables a considerable reduction in terms of computational complexity. The sampling distribution arises under realistic assumptions on the indoor ultra-wideband radio channel. Through simulations, we show that the proposed sampling distribution enables reduced complexity and results in faster convergence when compared to typical sampling distributions from literature.enConference PaperOther
