The Bdual-Tree: indexing moving objects by space filling curves in the dual space
Abstract Existing spatiotemporal indexes suffer from either large update cost or poor query performance, except for the Bx -tree (the state-of-the-art), which consists of multiple ...

Analog Joint Source Channel Coding Using Space-Filling Curves and MMSE Decoding
We investigate the performance of a discrete-time all-analog-processing joint sourcechannel coding system for the transmission of i.i.d. Gaussian and Laplacian sources over AWGN c...
